expression of animating colors

[Dan Ebberts]

If you’re using the Fill effect, this should give you a random color:

seedRandom(index,true);
random([0,0,0,1],[1,1,1,1])

thanks for the reply Dan.
I don’t know which effect to apply here. but i tried to pull the fill effect onto one of the rings, and click on the color property under fill to add expression to it.
but the color does not change. then i tried to set keyframes with different colors on the timeline. but still nothing happens.
do you have any clue about that?

Did you successfully add the expression to the fill color (the expression is there and enabled)? When you apply the fill it defaults to red. Are you saying that it stays red when you apply the expression?

Hi
I tried the expression as well and it only works when I change the word true to false.
Color changes now every frame.I’d like to change color every second for example,what’d be the code?
Thx

Hey Dan
Yes it stayed red. But when I changed true to false it does work. It would be nice if it can change slower, like twice a second. Do you know how that can be done?

Thanks

Try this:

posterizeTime(2);
random([0,0,0,1],[1,1,1,1])

[Dan Ebberts]

Like this:

posterizeTime(1);
random([0,0,0,1],[1,1,1,1])

Change the posterizeTime value for a different rate.

Hi there

Is there any way of applying this to the scale property? So that you have, say, a few different blocks which expand and contract randomly at a moderately slow (ambient) pace?

Many thanks!
