However you will notice that since there are only 3 combinations (additionally proven from 3!2 = 3), this leaves a gap, which would be where yellow sits. You could implement something along these lines, but I feel it looks a little wrong:

I am just wondering if some people have some insight as to how to determine the proper coloured square to fit into that spot. I also have some suspicion that this is not actually possible, just by the nature of the RGB system, and should be more appropriately displayed as a circle, connecting the two yellow sections.
If people want my current code, I have no problem sharing it!
If each corner has to represents a primary colour, the rectangle shape doesn’t seem to fit unless you break loose from the ‘corner idea’. It’s not without reason that they often use triangles to represent colour systems such as RGB. You seem to be aware of this though, and as I understand it you’re trying to experiment with the possibilities.
It might be inspiring to study some other colour systems. There are a lot of interesting ones out there which never became as famous as RGB. Perhaps one of these is playing around with a rectangle shape as well to represent a colour spectrum.
ps. If you’re really fond of your ‘corner idea’, perhaps you could use the right bottom for dark colours/shade?
Yes, I rather feared as much. Just trying some stuff out, never did too much colour theory. Was thinking where HSB might take me, but I think it won’t be that interesting. Looking into other colour schematics would be interesting!
Doubt I’ll do the dark bottom for dark colours/shades, but I will probably look into making this into some sort of ring or circle, or a triangle like you suggested.
