An essential quality of color is temperature. Temperature can be used to attain a color balance. Temperature can be used to enhance spatial relationships within an image. Temperature can be used to elicit psychological responses within the viewer. Understanding and exploring the dynamics of temperature in color can benefit any visual artist.<\/p>\n

There are physical characteristics of color linked to temperature. The color temperature of light (Kelvin degrees) is determined by measuring a black body radiator (an object heated so that it emits light). As the physical temperature of the object rises, color transitions from red (long wavelengths \u2013\u00a0low energy) to blue (short wavelengths \u2013\u00a0high energy) through ROYGBIV (red, orange, yellow, green, blue, indigo, violet). When it comes to light sources, physically, blue is warmer than red.<\/p>\n

There are also psychological qualities of color linked to temperature. Psychologically, blue is cooler than red. These associative qualities of color with regard to temperature are almost universally accepted. This is due in large part to our physical environment \u2013 water is blue, plants are green, sunshine is yellow, fire is red.<\/p>\n

Using the qualities of one sense (touch) to describe the qualities of another (sight) can be a tenuous affair and may lead to ambiguity and confusion. The more precise a language is the more useful it is. The language of HSL (hue, saturation, luminosity) is a very precise language. When using the language of HSL, hue values mark a position measured in degrees on a color wheel. A circle has 360 degrees, so the scale is 0 – 359.<\/p>\n

While every degree represents a new hue, you can use broader terms to describe a color family; red, orange, yellow, etc. Think of the color wheel as a clock where every hour marks a new color family.<\/p>\n

Absolutely warm and cool colors can be found at 0 (red \u2013 the warmest color) and 180 (cyan \u2013\u00a0the coolest color) degrees. Determining whether one color is warmer or cooler than another can be measured by their proximities to these poles. A line between 90 (green yellow) and 270 degrees can be used to broadly demarcate warm colors from cool colors; colors on the right (towards red) are warm while colors on the left (towards cyan) are cool. The association of yellow with the sun, a warm light source, subtly skews the associative quality of warmth towards yellow (60) and away from blue; as a result, colors above the line between 0 and 180 tend to seem warmer than colors below it. (i.e. while both are equally distant from red (0), orange (30) seems warmer than blue red (330).) While one color can be seen as warmer or cooler than another color, each color also has warm and cool components; there are warm yellows and cool yellows, warm blues and cool blues, etc. (Where numerical classifications of colors define hues very specifically (1 degree per hue, 30 degree spread per linguistic color), linguistic specifications of colors (red, orange, yellow, etc) define broad ranges of hues.) Defining the warm and cool endpoints of any linguistic color is useful at a coarse level of granularity but becomes increasingly subjective at a fine degree of granularity. At what point does blue become purple? At what point does blue become green?<\/p>\n

It’s possible to describe the adjustment of hue simply in terms of warming and cooling.<\/p>\n

Photographic color adjustment strategies rely on adjusting a balance in each of three complements.<\/p>\n

Red \u2013\u00a0Cyan
\nGreen \u2013\u00a0Magenta
\nBlue \u2013\u00a0Yellow<\/p>\n

\"colorbalance\"<\/a><\/p>\n

Most hue adjustment tools, like Photoshop\u2019s Color Balance, have these complements built into their interface. You can\u2019t increase one hue without decreasing its complement.<\/p>\n

Each set of complements has a warm and cool dynamic.<\/p>\n

R (warm) \u2013\u00a0 C (cool)
\nG (cool) \u2013\u00a0 M (warm)
\nB (cool)\u00a0\u00a0 \u2013 Y (warm)<\/p>\n

These three complementary axes have different warm\/cool dynamics with respect to the three color primaries – RGB.<\/p>\n

red (warm red) \u00a0 \u00a0 \u00a0\u2013 \u00a0 cyan (cool blue) \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 warm\/cool
\ngreen (cool green) \u2013 \u00a0 magenta (cool red) \u00a0 \u00a0 \u00a0 cool\/cool
\nblue (warm blue) \u00a0 \u2013 \u00a0 yellow (warm green) \u00a0 \u00a0warm\/warm<\/p>\n

You can analyze the color temperature dynamics at work in any image by sampling it and graphing it. Doing this will not only help you understand how it works\u00a0but also how you might improve it.<\/p>\n

You can make a field of color appear more dynamic, complex, and three-dimensional by preserving or introducing a variety of warm and cool components in it.<\/p>\n

The temperature of color carries spatial associations with it. Warm colors tend to appear to be nearer than cool colors. Again this is universal. It can be overturned by many factors; some factors are related to color, such as saturated colors appear nearer than desaturated colors or a progression from light to dark may be the primary element that establishes spatial hierarchy; some factors are not related to color, for instance, placement and overlap in the composition may be primary spatially, overriding color relationships.<\/p>\n

Color balance, spatial proximity, association \u2013 these are just three of the uses of warm and cool color dynamics in images.<\/p>\n

Whether you are adjusting preexisting color relationships or creating new ones, having thoroughly explored the warm and cool dynamics of hue, you can apply that knowledge towards the realization and enhancement of your images.<\/p>\n
