Color Correction Curves image effect
Color Correction Curves image effect changes the color buffer simply by tweaking curves for each color channel. Depth based and selective color correction is also available.
As with the other image effects, this effect is only available in Unity Pro. Make sure to have the Pro Standard Assets installed.
Color correction curves can change foreground and background individually.

Hardware support
Color correction curves effect works only on graphics cards with support for pixel shaders (2.0) or devices with OpenGL ES2.0 support. Eg. GeForce FX 5200 or Radeon 9500 and up. All image effects automatically disable themselves when they can not run on an end-users graphics card. Depth texture support is only required when depth based color correction is enabled.
