Since the “distributions” in that playground are just sequences, you could add .lazy.map({ Color(value: $0) }) to transform an integer-producing distribution into a color-producing one. (Which is pretty cool, tbh.)

See my other email for details, but it is essentially initialized from a sequence of 2-4 UInt* (one for each axis).  I usually fix all but one dimension for aesthetic reasons though, so yes-ish**.


* I do mean UInt, and not UInt32 or UInt64. The amount of randomness it grabs is based on the word size of the platform, since CGFloats are as well.

** It currently naively still burns 2-4 UInt worth of randomness even if the axises are fixed, but it is ignoring 1-3 of the numbers in that case and only really using 1.  I could easily optimize this without changing the interface though.
