Channel Blur
Gives you control over blurring each color channel of an object. The Channel blur can
be applied selectively to each of the different color channels of the object: red, green,
blue, and alpha.
Blurring individual channels allows you to create customized glow effects by retaining
sharpness in selected channels while softening others.
