eli5 What makes the color green, green?

612 views

Hello all,
I am working on a project that requires me to identify what colors are green. This seems easy enough but I am working with color codes and don’t know where certain colors start and/or cut off.
I am working with RGB and a color can appear completely red with a value of 1 for Green but not appear green at all. Would this still be called green?

In the RGB colorspace, “all green” is 552 ± 1 nm (I’m remembering 552, and I can’t seem to find the reference right now).

When you have green at 1 and the other colors at 0 you should have green, or your display is malfunctioning.

When you have green at 1 and red at 1 and blue at 1 you should have white, or your display is malfunctioning.

So, just because green is 1 it isn’t supposed to imply the result is green.
