These are subtractive colors applied to a white background.
Primary colors for computer displays are Red, Green, Blue.
These are additive colors, each may be 0.0 to 1.0 floating point,

RGB 0,0,0 is black, 255,255,255 is white, 255,0,0 is red
Primary colors for color printers are Cyan, Magenta, Yellow.
These are subtractive colors applied to a white background.
There is also typically Black.
Color TV uses a very different method, YIQ that has
intensity Y, and uses phase angle IQ for color.
Not all RGB colors can be converted to YIQ.
An RGB image can be shown as gray scale, 0.0 to 1.0,
using 0.299 *R + 0.587 *G + 0.114 *B
A fourth byte may be used to get 32 bit color, RGBA,
the A is alpha, 0 is transparent, 255 is opaque,
128 or 0.5 allows some of another image to come through.
Toolkits such as OpenGL with GLUT are available on
all operating systems.
