Synonym for the RGB (red, green, blue) color space that uses the projected
red, green and blue light as primary colors to produce the full spectrum
of colors. Any color can be produced by adding the colors of the three color
channels RGB (Red, Green, and Blue). If the colors of two of the color channels
are mixed in equal proportions, new base colors are created. Blue and green
add up to a bright, light blue called cyan. Magenta, a bright pink, is made
by mixing red and blue. Red and green together make yellow. If red, green,
and blue light are mixed equally together at full power, you get white light.

is the vibrance, intensity or purity of a color. As a color moves away from
gray, it becomes brighter. Same as saturation.
Color schemes are harmonious color combinations that use any two colors opposite
each other on the color wheel, any three colors equally spaced around the
color wheel forming a triangle, or any four colors forming a rectangle (actually,
two pairs of colors opposite each other).
There are six classic color schemes: Monochromatic, Analogous, Complementary,
Split Complementary, Triadic, and Tetradic (also called Double Complementary).
See Color Schemes for

Colors that add to white when mixed adaptively. Complementary colors reside
at opposite ends of the Color Circle or Color Wheel. There is a unity inherent
in using complementary colors since any color has as its complement the sum
of the other two primary colors. The complement of yellow, for instance is
purple, made by mixing the other two primaries, red and blue. The complement
of red is green, a combination of yellow and blue. Compositions created using
complementary color schemes tend to feel complete and pleasing to the eye.
Complementary colors will desaturate each other if mixed. Examples: Magenta-green,
blue-yellow, red-cyan

The color in its purest form, with no black, gray, or white added. For example,
scarlet, crimson, and pink have the same hue - red. You can see hues on
the outer edge of the color wheel and in the spectrum.
The 'blackness' or 'whiteness' of the color. In terms of Color Wheel Pro, black
has the lightness of -1, pure hue has the lightness of 0, and white has the
lightness of 1:

White, black, gray and colors containing a significant amount of gray.
The basic colors that can be mixed to make all other colors. The primary colors
cannot be made by combining other colors.
Mixing primaries: Red, yellow, blue (RYB)
Visual additive primaries: Red, green, blue (RGB)
Visual subtractive primaries: Cyan, magenta, yellow (CMY)
The amount of hue in proportion to the neutral gray of the same lightness,
that is the intensity of color. In this example, the leftmost swatch has
the saturation of 1 (maximum value) and the rightmost swatch has the saturation
of 0 (minimum value).

Colors that are made by mixing two adjacent primary colors. For example, red
and blue light mixed give magenta light.
Mixing secondary colors: Orange, violet, and green (according to Johannes Itten)
Visual additive secondary colors: Cyan, magenta, and yellow (CMY)
Visual subtractive secondary colors: Red, green, blue (RGB)
Shades are mixtures of a hue and black. This example shows five different shades
of red:

The opposite of additive color mixing, subtractive color mixing describes how
the light absorbing properties of paints mix to make colors in reflected
light. This color mixing is explained through combinations of the three subtractive "primary" colors
cyan, yellow and magenta (CYM), and is usually demonstrated by placing multiple
color filters over a single beam of light, or by physically mixing paints
(i.e. inks or pigments that reflect light of a certain color). That is, the
subtractive primary colors result when a section of the visible spectrum
corresponding to a single additive primary color is absorbed from reflected
white light.

Tints are mixtures of a hue and white. This example shows
five different tints of red:

Tones are mixtures of a hue and its complement or grays. This example shows
five different tones of red:

is a color's lightness or reflectivity as measured against a gray scale from
white to black. The higher the Light Reflectance Value (LRV), the more
reflective the color.
