Color the visible spectrum aka spectral hues
Color: the visible color is contained in sunlightspectrum, aka Spectral Hues


Additive color
Additive color color is contained in sunlight


We see color when wavelengths are interrupted by matter
We see color when wavelengths are interrupted by matter. color is contained in sunlight

In the case of a green leaf, all colors in sunlight are absorbed into the leaf except for green, which is reflected toward our eyes. If all wavelengths are absorbed we see black. If all wavelengths are reflected we see white.


Subtractive colors
Subtractive colors color is contained in sunlight


P r i m a r y colors
P color is contained in sunlightrimaryColors

  • RED

  • BLUE

  • Yellow

    These are the primary colors in the subtractive (pigment based) color system. Mixing two primary colors produces Secondary colors: Orange, Green, Purple. Primary colors cannot be mixed from other colors.

HUE color is contained in sunlight

  • The color quality identified by a color’s name. This is determined by a color’s wavelength.

  • Any of these colors fall under the general hue red.


Saturation
Saturation color is contained in sunlight

  • The purity of a color, how ‘true’ it is. A color with no white, black, gray, etc added is said to be at Full Saturation.


Value: light or dark in colors color is contained in sunlight

Colors have inherent values. In these Chromatic Value Scales the step at Full Saturation (full purity) arrives at different point in each scale. In yellow, it is step 4, red: step 7, blue: step 9. This is because pure blue is inherently darker than pure yellow.


  • TINTS color is contained in sunlight: Color + White

  • Shades: Color + Black


Monochromatic color schemes
Monochromatic color schemes color is contained in sunlight

A combination of colors based on variations of value and saturation of a single hue. Perhaps some neutrals are also included to add variety and contrast.
