So this expression changes a layer's colour based on its rotation angle?

That works.

Thanks much,

I think you need an == instead if =

if (r == 0) color2/255 else color1/255

I am trying to modify this expression, which works:

color1 = [204,0,0,255]; // shade of red + alpha
color2 = [0,204,0,255]; // shade of green + alpha
r = thisComp.layer("shape").transform.rotation;
if (r > 0) color2/255 else color1/255

To this expression, which does not (only the = sign in the last line is different):

color1 = [204,0,0,255]; // shade of red + alpha
color2 = [0,204,0,255]; // shade of green + alpha
r = thisComp.layer("shape").transform.rotation;
if (r = 0) color2/255 else color1/255

Any suggestions on how to proceed?

Thanks,

James
