What’s wrong with this non random color array picking expression?
I am getting syntax error and I am pretty sure it’s either the double bracket or the slider value didn’t get translated when putting into options?
Thanks.
R1=thisComp.layer("color").effect("R1")("Slider");
G1=thisComp.layer("color").effect("G1")("Slider");
B1=thisComp.layer("color").effect("B1")("Slider");
options = [[R1],[G1],[B1], 255], [0, 255, 0, 255], [0, 0, 255, 255]];
seedRandom(index, true);
r = Math.floor(random(3));
options[r]/255; -

No need to put the individual slider values in brackets (Plus you were missing one opening bracket for the first set of colors).

you mean like this? that’s the first I try but it don’t work either 🙁
R1=thisComp.layer("color").effect("R1")("Slider");
G1=thisComp.layer("color").effect("G1")("Slider");
B1=thisComp.layer("color").effect("B1")("Slider");
options = [[R1,G1,B1, 255], [0, 255, 0, 255], [0, 0, 255, 255]];
seedRandom(index, true);
r = Math.floor(random(3));
options[r]/255; -
Yes, it works just fine like that. Perhaps it just does something different from what you expect? It picks one of those three color values at random. It just does that once per layer, so if you duplicate the layer a number of times, the property will result in different colors wjhere this expression is used.
