To do this you'd need 10 different tiers of transparency in the colorset for each color. You'd only be able to get like 5 colors with 10 different transparencies.
5*10=50
Limit is 64, not 50. He also said 10 would be invisible, and if it's invisible the color doesn't matter aside from tinted emitters. Unless you're worried about that, it'd be nine colors per color plus one extra. 9*7=63, plus totally transparent is 64, so only 7 colors. Still a ridiculously low number of colors.
maybe it can be done by rapidly oscillating between turning rendering on and off
its a terrible solution but still
I thought of this. Lag would be an issue, wouldn't it, since the server would have to send every switch to the client? If it's going too fast even a little bit of latency will cause obvious visual issues
