Yellow is the one that's out of place. If you want subtractive primaries, you'd need cyan, magenta (which doesn't exist in pyramids yet), and your maligned yellow. So now adding the white to the additive primaries and black to the subtractive primaries, where do you make room for the other colors? We've assumed a new magenta color and we've left out orange and purple from existing colors. I'd say we can assume clear doesn't exist in this exercise. ;) Oh, and to actually contribute to this thread, I believe that Andy's original mapping is the best. Red -> Orange, Yellow -> Clear are obvious mappings. Blue -> Cyan means that you have a head-scratcher with Green -> Purple. Blue -> Purple makes sense looking at the pyramids side by side, and that leaves Green -> Cyan, which is non-obvious objectively (Dark Blue/Light Blue thing), but you can make sense of it if you think of Cyan as Blue-Green. Oh, and for what its worth, I was in James's camp until I actually looked at them side by side. Academically, Blue -> Cyan seems obvious, but aesthetically, James's Green -> Purple mapping is jarring (maybe that's why the Drazi fight their civil war?), and the gestalt of Andy's original mapping is pleasing.
