Image Control>Colorama is the most advanced color correction/color enhancement/color effect plug-in that ships with After Effects. It works by stripping all of the original color from the image and applying new colors. You can see the new colors it is applying by twirling open the Output Cycle parameter group .
Anything that was originally black in your image will be mapped to the top of the color wheel, which is red by default. Formerly black things in your image will be red. Then, as the original colors get lighter and lighter, they will be mapped to other colors on the Output Cycle wheel, traveling clockwise around the wheel. White, like black, will also be mapped to red, at the top of the wheel.
To change colors on the wheel, double click any triangle (color stop) around the wheel.
To delete a color stop, drag it away from the wheel.
To add a new color stop, click anywhere on the wheel where there isn't already a color stop.
Cmd+drag (Ctrl+drag) a color stop to copy it to a new location around the wheel.
Or, choose cool wheel presets from the Use Preset Palette dropdown.
