So I was just playing around with the ColorSet effect, and was trying some random values, but when I compare the numbers to the pallet of colours the numbers seem a bit off.
The Red, Green, Blue values are fine, but it's when you use the Random number generator, things go screwy. I've used int(random(255)) to generate the values, and have attached a .capx as well. It's not super urgent, but it just seems strange for it to return the colour it is.
