creating a rand expression for rgbPP for particles systems..

[svenip]

particleShape1.rgbPP = <<rand(0,1),rand(0,1),rand(0,1)>>

just change the name to your particleShapeObject name (particleShape1)

better would be to work with a ramp (better control over the things) :bounce:

And remember to write this expression in creation, otherwise your particles will change color every frame.
