Color blinking expression
Hello!
I feel like this is a simple expression and I’ve tried writing it but with no luck.
Basically, I’m trying to have a color fill in a shape layer blink between two colors.
I have this expression for blinking but not sure how to apply it to color fill:
blinkSpeed =30;
n = Math.sin(time*blinkSpeed);
if (n<=0) 0 else 150;My guess is that the “0” should be the first color information and the “else 150” part should be the other colors information?
Any help is much much appreciated!

Your guess is correct. It would be like this for red and blue:
blinkSpeed =30;
n = Math.sin(time*blinkSpeed);
if (n<=0) [1,0,0,1] else [0,0,1,1];Or, if you don’t want to use the normalized RGBA color channel values, you could do it like this:
blinkSpeed =30;
n = Math.sin(time*blinkSpeed);
if (n<=0) [255,0,0,255]/255 else [0,0,255,255]/255;Dan
