A monochromic[1] image is composed of one color (or values of one color).[2] The term monochrome comes from the Ancient Greek: μονόχρωμος, romanized: monochromos, lit.'having one color'.
One Color Challenge
A monochromatic object or image reflects colors in shades of limited colors or hues. Images using only shades of grey (with or without black or white) are called grayscale or black-and-white. However, scientifically speaking, monochromatic light refers to visible light of a narrow band of wavelengths (see spectral color).

Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ('blueprint') images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image.
In computing, monochrome has two meanings:
- it may mean having only one color which is either on or off (also known as a binary image),
- allowing shades of that color.
A monochrome computer display is able to display only a single color, often green, amber, red or white, and often also shades of that color.
In film photography, monochrome is typically the use of black-and-white film.Originally, all photography was done in monochrome. Although color photography was possible even in the late 19th century, easily used color films, such as Kodachrome, were not available until the mid-1930s.
In digital photography, monochrome is the capture of only shades of black by the sensor, or by post-processing a color image to present only the perceived brightness by combining the values of multiple channels (usually red, blue, and green). The weighting of individual channels may be selected to achieve a desired artistic effect; if only the red channel is selected by the weighting then the effect will be similar to that of using a red filter on panchromatic film. If the red channel is eliminated and the green and blue combined then the effect will be similar to that of orthochromatic film or the use of a cyan filter on panchromatic film. The selection of weighting thus allows a wide range of artistic expression in the final monochromatic image.
For production of an anaglyph image the original color stereogram source may first be reduced to monochrome in order to simplify the rendering of the image. This is sometimes required in cases where a color image would render in a confusing manner given the colors and patterns present in the source image and the selection filters used (typically red and its complement, cyan).[3]

In physics[edit]
In physics, monochromatic light is electromagnetic radiation of a single frequency. In the context of physics, no source of electromagnetic radiation is purely monochromatic, since that would require a wave of infinite duration as a consequence of the Fourier transform's localization property (cf. spectral coherence). Even very controlled sources such as lasers operate in a range of frequencies (known as the spectral linewidth). In practice, filtered light, diffraction grating separated light and laser light are all routinely referred to as monochromatic. Often light sources can be compared and one be labeled as “more monochromatic” (in a similar usage as monodispersity). A device which isolates a narrow band of frequencies from a broader-bandwidth source is called a monochromator, even though the bandwidth is often explicitly specified, and thus a collection of frequencies is understood.

The word color is the general term which applies to the whole subject -red, orange, yellow, green, blue, violet, black and white and all possiblecombinations thereof. Hue is the correct word to use to refer to just the pure spectrum colors. Any given color can be described in terms of its value and hue. In additon, the various physical phenomena and pyschological effects combine to affect our perceptions of a color.
Value and Hue
Value is defined as the relative lightness or darkness of a color. It is an important tool for the designer/artist, in the way that it defines form and creates spatial illusions. Contrast of value separates objects in space, while gradation of value suggests mass and contour of a contiguous surface. In the drawing on the right, value contrast separates the artichoke from the background, and the separate leaves from one another, while gradation suggests the curves of leave surfaces and of the whole form.
Hue also has value. When contrasting hues are made similar in value, the spatial effects are flattened out. The pair of images on the left demonstrate this. In the color image of the fashion model the coat draws our attention through contrast of hue although the skin tones blend with the background(remember the object of the image is to sell the coat, not the model). However, it also seems to be softly blending with a background that seems quite close, and is very similar to the coat in value. The face tends to blend with the background which is similar in both hue and value. In the black and white version, however, the coat virtually disappears, since only value, not hue, are available to distinguish it, and the values are quite similar. However, the strong value contrast of the eyes and hat draw our attention to the face, even though the contours of the face seem to melt into the background. Therefore the black and white version emphasizes the model more than the garment.
To summarize: If values are close, shapes will seem to flatten out, and seem closely connected in space; none will stand out from the others. If values contrast, shapes will appear to separate in space and some will stand out from the others. This works whether the colors are just black, white and gray, or whether hues are involved.
Hue is the term for the pure spectrum colors commonly referred to by the 'color names' - red, orange, yellow, blue, green violet - which appear in the hue circle or rainbow. Theoretically all hues can be mixed from three basic hues, known as primaries. When pigment primaries are all mixed together, the theoretical result is black; Therefore pigment mixture is sometimes referred to as subtractive mixture.
The primary colors consist of three hues from which we can theoretically mix all other hues. There are two commonly used definitions of primary colors:
Painters Primaries - red, blue, yellow: This traditional definition of primaries does not in fact mix to clear greens or purples; it is based on 19th century theories.
Printers Primaries - magenta, cyan (turquoise), yellow: This definition of primaries mixes to clear colors across the entire spectrum. It is used as the basis for color printing. The computer screen probably does not give you a true turquoise--the color should be a blue-green-- because of differences between color mixture in pigment and color mixture in light.
In mixing colors hues can be desaturated (reduced in purity, weakened) in one of three ways: mix with white to lighten the value (tint), mix with black to darken the value (shade), or mix with gray or the complement to either lighten or darken the value ( tone).
Light Primaries - red, blue, green. This definition is active when colored light is mixed, as on your computer screen, or when theatrical spotlights overlap on a white wall. Its effects are lessfamiliar than pigment mixture to most people. If all three primaries are mixed,the theoretical result is white light. Therefore Light mixture is sometimesreferred to as additive mixture.
Your computer screen mixes color as light, and therefore follows additive color mixture rules. Therefore it ispossible to check how additive mixture works on your computer screen--try this link to an interactive additive color mixture tool. When you get there, click on the button below the moving primary circles, then see what happens when you slide them around.This means that the depiction of subractive mixture shown here is less than ideal, particularly for the cyan (turquoise) and magenta of the printers primaries.
If you want to see some amazing animations of hue and value relationships, try going to this link, which will also take you to a good descriptive explanation of hues and primaries. Also here is a great interactive test of your ability to distinguish gradations of hue, created by Pantone.
There are many systems for classifying hue, developed so that researchers can measure and define color qualities, and so that designers, industry, and marketing people can communicate color ideas over distance. One example is the Munsell system; another is the Pantone System. However, today the communication of precise color information is mainly done digitally, using spectrophotometers to identify and transmit color information. These digital systems use additive (light) mixture rather than the subtractive (pigment or dye) mixture used in systems like Munsell and Pantone.
Complements are colors that are opposite one another on the hue circle. When complements are mixed with one another in paint, the resuting muted tones desaturate or dull the hues. Such opposite pairs can also be compared in terms of their relative warmth and coolness. Warm-cool contrast of hue can cause images to appear to advance or recede. In this 15th century painting, for example, the warm reds of the man's doublet and his son's cap reinforce the cues of placement to make these figures seem very close. On the other hand, the cool tones of the sea and sky suggest great distance.
Afterimage is another, more specific definition of complements consisting of astimulus color and its physical opposite generated in the eye byexposure to the stimulus color. Afterimage colors tend to make each other appear more intense, and have vibrating boundaries.
Color Illusions
Some of the effects of color occur only in the eye and brain of the viewer, and are not physical properties of light waves or pigment. These illusions, however, are very powerful, and have enormous impact on our responses to color.
Color Proportion refers to the impact of the relative quantity of a given hue or value used in color compositions. In order to achieve over-all unity, and/or create emphasis, one should make a clear decision as to which colors should be assigned the largest and least areas. The color proportion choice will also affect the impact of the color composition. This can be seen in the set of panels shown here. The very same colors are used in each panel. Yet depending on the choice of dominant color, the feeling of the composition, and even the appearance of each color, is altered.
Simultaneous Contrast is the phenomenon which occurs when a color appears to change when seen against adifferent background. A set of principles were first laid out in the 19thcentury by Chevreul, a dye master for the Gobelin tapestry works, who became animportant color theoretician. His principles state that changes in the hue,value, saturation (purity of hue), and area of a background color will alter the appearance ofthe selected color. The print shown here is made up of wavy bands of colors. Some of the bands extend from the center panel to intrude into areas of contrasting hue in the side panels. These extended bands are in fact the same hue and value throughout, but appear to change from left to right.
If you are interested in further information about how our visual response to color may vary, see this section on optical effects in color.
Optical mixture is the phenomenon which occurs when small particles of different colors are mixed in the eye; this type of mixture differs from pigment mixture in that it is based on light primaries. However,optical mixture differs from light mixture in which the primaries will mix to white, and from pigment mixture, in which the primaries mix to black. In optical mixture there is an averaging of hue and value, resulting in grey. Optical mixture is experienced when observing many textiles, such as this example, a detail from a handwoven tapestry. It can also be seen in natural objects, color television, and printed color pictures.

Market researchers have doneextensive studies exploring the emotional responses of people to color. Some of theseresponses seem to be powerful and fairly universal. However, much of thisinformation is culturally biased. We know that cultural traditions endow colorswith powerful meanings that can differ greatly from place to place. Forexample, in Europe and the United States, black is the color of mourning. Inmany tropical countries and in East Asia white is the color of death. On theother hand, white is the color worn by American brides, while brides in much ofAsia wear red. Based on research done in the United States and Europe,we know that the following associations are generallyfound to hold in Euro-American societies:
Red is associated with blood, and with feelings that are energetic, exciting, passionate or erotic. Most colors carry both positive and negative implications. The downside of red evokes aggressive feelings, suggesting anger or violence.
Yellow is the color ofsunshine. This color is optimistic, upbeat, modern. The energy of yellow can become overwhelming. Therefore yellow is not a color that tends to dominate fashion for long periods of time.
Green In its positive mode, green suggestsnature (plant life, forests), life, stability, restfulness, naturalness. On the other hand, green in some tones or certain contexts (such as green skin) might instead suggest decay (fungus, mold), toxicity, artificiality.
Blue suggestscoolness, distance, spirituality, or perhaps reserved elegance. Some shade of blue is flattering to almost anyone. In its negative mode, we can think of the 'blues'-the implication being one of sadness, passivity, alienation, or depression.
Violet is the color offantasy, playfulness, impulsiveness, and dream states. In its negative mode, it can suggest nightmares, or madness.
One Color Puzzle
Market research on color is also done to establish color trends. Colorforecasting is accomplished by surveying consumer preferences and otherindicators of changes in taste. Color forecasting firms then issue projectionsdefining palettes of colors that can be expected to rise, fall, or maintain popularity incoming seasons. The design industries then develop their new lines with theseprojections in mind. Some major companies employ their own color forecasters to research and project color trends for their industry. On the whole, color trends change more rapidly for fashion than for interior design, probably because changes in home furnishings entail a more serious financial investment.
