I hate starting-up/continuing one of these tangent discussions, but...

Red, green, and blue are the standard primary colors of light in what is
called a tristimulus color model. You can use other colors, and no one set
of three colors can produce the entire gamut of human-perceived color, but
red, green, and blue give the widest possible range.

When working with pigments, the best set of three colors contains magenta,
cyan, and yellow. These colors are what are used, with the addition of
black for improved contrast, in the standard four-color printing process.

For second grade art class, however, red is close enough to magenta, and
blue (more like a sky blue) close enough to cyan to satisfy the struggling
crayon and finger paint artists!
