The industry leading Color Palette for After Effects.
Currently, all the colors in your After Effect project have a fixed value, even if multiple colors in your scene have the same color value. This makes trying a different color or changing one almost impossible because you have to change each individual color of every element in the project. Ray Dynamic Color not only gives you a color palette to color with, it can also create clever links between the color values in your scene and the color palette. This give us many options to manage colors. Watch the tutorials to learn how.
