I'm using coloured lamps to colour-code areas of my Aquilo base (as in FFF-432), and noticed that when multiple pink (255,140,255) lamps were in the same area, they ended up emitting white light with just the outer lit region retaining the pink colour.
Monochrome R, G, B, and C, Y, M lights don't have this issue (because they only use values of 0 and 255), and when testing by placing 12 almost-red (255,20,0) lights together, they end up emitting yellow with a red border, as I'd expect from 12*(255,20,0) = (3060,240,0) -> (255,240,0)
