Do you really think green is a primary color, you great braying
jackass?

Green is a primary color - RGB

However, what is primary for one discipline is not primary for another
discipline. For instance, in color photography and in its negatives,
the colors are Cyan, Magenta, and -ahem- Yellow. This is the
difference between additive primaries and subtractive primaries.

These colors are actually dual band modes
Cyan is Blue + Green
Magenta is Blue + Red
Yellow is Green + Red

There is also the opponency color system that contains, as colors,
Red, Blue, Green, and Yellow.

However, color is a perception and has absolutely no connection to
sub-atomic leprechauns. All light emanates from electron orbital
displacements (aka charge acceleration).
