  • Expression to change layer color when hit edge of comp

    Am trying to find an expression that will change the hue of a layer when the layer hits the edge of a comp. Like the DVD screensaver here:

    I have a hue/saturation effect on the layer and would like for it to randomly change the colorize hue parameter of the effect.

    Thanks in advance!

    How are you generating the motion? Your expression is going to have to calculate when the logo last hit an edge and use that time as a random seed so that the color will remain the same until the next collision.
