uniformdeviate returns a random number between zero and the value of the argument. So you do not want (uniformdeviate i).
Ah, that explains it. Thanks a lot Alan! Otared Kavian wrote:
One way is to increase the « degree of randomness » by saying withcolor transparent (1,0.3,mycolor[round(uniformdeviate(10*i)/10)]) or you can define a RandomColor as below:
I hate myself for not knowing more about math! I don’t see how mp picks its random numbers - when I recompile, I always get the same colors in the same order. They are “random” in the sense that there is no fixed order, but I was surprised that every run produces the same random order. RandomColor is nice, but not for my current purpose because I want to choose from a fixed list (colors are used as backgrounds, so I can only use dark colours, e.g.). Thanks a lot! Thomas
