Cool/Warm Contrast: a contrast in temperature
The color wheel is divided into "cool" colors and "warm" colors.
Cool: yellow-green, green, blue-green, blue, blue-violet and violet are cool. They carry with them associations of: shadows, transparency, sedation, airy, far away, light wet.
Warm: yellow, yellow-orange, red-orange, orange, red and red-violet are warm. They carry with them associations of: sun; opacity; stimulation; density; nearby; heaviness, dryness.
Red-orange and blue-green will always look respectively warm and cool. The hues in between will change in temperature depending upon what is placed next to or around them. Cool colors tend to give the impression of receding in space; warm colors will advance.
Select a cool/warm color scheme from the three options below:
Option I - Cool/warm modulation in red-orange. Use red-violet, red, red-orange, orange and yellow-orange.
Option II - Cool/warm modulation in blue-green. Use blue-violet, blue, blue-green, green and yellow-green.
Option III - Polar contrast. Use blue-green, blue, violet, red and red-orange.
When a composition is to be done in a particular contrast, all the other contrasts should be minimized or not used at all. All of the colors should therefore be equal in value rather than very light or very dark. Use white to adjust values to be =. Use medium/light values rather than very light or very dark.
Assign the colors to the contour map in a way that enhances the effect of elevation.
