rgbPP change @ every collision

[ruchit]

Here is my setup
*one directional emitter in neg y direction with speed of 2.0 & speed random=0.9
*creation expression in rgbPP as rgbPP=sphrand(2);
*lifespan 4 ever
*bounce=.25,friction=0
*color of particle rand only @ birth bcz of creation expression
And my doubt is
*how to change color of per particle @ every collision to surface (color will rand for each particle @ the time of collision)
*and after change in color the value of rgbPP remain same till next collision for that particle.

When you use the collision editor.
you can use the attribute event that is equal to the number of collision
