Ray Dynamic Color 1.0 - AEScripts

How it works:
Currently all the colors in your After Effect project live in their own place, even if some elements in your scene have the same color. When you want change or try a different color it's almost impossible because you have to change each individual color of every element in the project. Imagine if all the elements that share the same color have the ability to be dynamically linked to one color source. This would give us many options to manage colors.

With Ray Dynamic Color you can assign a number to the elements in your scene with one click. These numbers can then be represented by any color.

Compatibility After Effects CC 2014, CC, CS6, CS5.5, CS5
