About colors
RGB and CMYK models
Have you ever wondered why the world surrounding us appears colored to our eyes?
Light is electromagnetic waves with wavelengths between about 380 - 780 nm, also called visible rays. The
wavelengths of visible rays can be separated into the rainbow colors violet, indigo, blue, green, yellow,
orange, and red, from the shortest wavelength in order. When all the wavelengths of the visible rays strike
your eye at the same time, white color is perceived.
We see the objects in color because they reflect or transmit visible light of different wavelengths or
frequencies.
The colors separated from visible light are called primary colors. Primary colors cannot be produced from
other colors. These colors, however, can be combined to make up any other color (color mixture).
The color mixture provides two different types, three primary colors of light and three primary colors of
pigment.
The three primary colors of light are called additive color mixture, and the more colors are added, the brighter
it will be. Mixing red (R), green (G), and blue (B) colored lights, various colors can be created.
The three primary colors of pigment are called subtractive color mixture, and the more colors are added, the
darker it will be. Various colors can be created by mixing cyan (C), magenta (M), and yellow (Y) pigments (such
as ink or toner), however, black (K) is actually used as the fourth color in addition to the three primary
pigments.
