COLOR and LIGHT

Gillerman

 

Color systems are constructs with generally predictable sets of rules, but there are many different systems of color – and …  LIGHT and PIGMENT act very differently.

PRIMARY COLOR: is a color that cannot be created by mixing other color

PIGMENTS and LIGHT act differently and have DIFFERENT PRIMARY COLORS.

 

Pigment is referred to as Subtractive color

Light is referred to as Additive color

PIGMENT

Primary Colors: Red, Yellow, Blue

Compliments: Green, Violet, Orange (secondary colors)

(Red-violet, Blue-violet, Blue-green, Yellow-green, Yellow-orange, and Red-orange are tertiary colors)

Subtractive |  Absorb or Reflect Light - R + Y + B = BLACK/MUD (INK/Pigment)

LIGHT

Primary Colors: Red, Green, Blue

Adding R + G light makes yellow (Y).

G + B = cyan (C) and R + B = magenta (M)

Combining all three additive primaries makes white light.

Additive  |  R + G + B = WHITE LIGHT

PRINT (pigment)

Subtractive Primaries: Cyan, Magenta, Yellow

The subtractive primaries are C, M and Y. Cyan absorbs red; hence C is sometimes called "minus red" (-R). Similarly, M is -G and Y is -B.

CMYK: K = "Key" (sometimes Black)

PRISM (Solid Glass Optics)

White Light (Sunlight) enters the prism and is separated into different wavelengths of component colors,

the solar light spectrum, colors in a Rainbow.

Red, Orange, Yellow, Green, Blue, Indigo, Violet

(Realized first by Sir Isaac Newton - 1666)

The Solar Light Spectrum

Rainbow colors are created when raindrops refract the light from the sun into a color spectrum. A prism does the same thing.

R  Y      B  V
Red, Orange, Yellow, Green, Blue, Indigo, Violet

Light travels in waves of different lengths. The "Visible Light Spectrum" of light and colors we see are only a small part of the "electromagnetic spectrum".
