That triangular diagram with red, green and blue at the corners
and white in the middle, and intended to show every possible colour that can
be derived from additive mixing of those three
colours, is called a chromaticity diagram. It famously used to be
used to show that a colour CRT cannot (truly) produce brown.


You've never seen a '70s RCA set? Brown was about the only color it /could/
produce (along with some blues and yellows, if I recall correctly).

Brown is actually a very dark red.
