• Adobe After Effects Expressions

  Change color value once a slider passes a given value.

  Posted by Jonathan Ficcadenti on September 10, 2013 at 12:51 am

  Hello CC community,

  I apologize in advance if some one else has already answered this question, but:

  I need an expression that does the following:
  If the value of a given property (in this case, a slider control) exceeds a certain value (for example, 75), then a separate color control value would switch from color 1 (white) to color 2 (red).

  Thank you in advance for your help with this.

  Something like this maybe:

  s = effect(“Slider Control”)(“Slider”);
  c1 = [1,1,1,1]; // white
  c2 = [1,0,0,1]; // red
  if (s > 75) c1 else c2
