Randomize color of words in a text layer based on specific color controls effect
Hello everyone !
I’m facing a little problem. I want to randomly change the color of words in a text layer, no need to animate the change of color, but I want the colors to be randomly picked from a list of Color Control effects.
This expression is working if applied to a color parameter, but – as you can see on the screen capture – when it’s applied to the Expression selector of a text Animator, I get this error.
“expression result must be of dimension 3 not 4”
I guess it’s because the value of each variable “var color…” also include the Alpha value.
Any help would be very welcome, thank you guys.

If your text is black and the fill color animator is white, this should work:
color1 = effect("Color Control 1")("Color");
color2 = effect("Color Control 2")("Color");
color3 = effect("Color Control 3")("Color");
color4 = effect("Color Control 4")("Color");
color5 = effect("Color Control 5")("Color");
colors = [color1,color2,color3,color4,color5];
slider = Math.floor(effect("Slider Control")("Slider"));
c = colors[slider];
[c[0],c[1],c[2]]*100 -
Hey hello Dan, and thank you so much for your swift answer ! 😉
I just tried and it seems it works on the global color of the text layer, but it’s not changing the words color randomly.
Here’s a screen capture of the different expressions I’ve found on several websites.
Many thanks !

Ah, sorry. I got distracted by the slider. Try it this way:
color1 = effect("Color Control 1")("Color");
color2 = effect("Color Control 2")("Color");
color3 = effect("Color Control 3")("Color");
color4 = effect("Color Control 4")("Color");
color5 = effect("Color Control 5")("Color");
colors = [color1,color2,color3,color4,color5];
seedRandom(textIndex,true);
i = Math.floor(random(colors.length));
c = colors[i];
[c[0],c[1],c[2]]*100 -
Works like a charm !
Dan’s magic again 🙂
Thank you so much !
