Are there any instances where chromatic aberration can be properly used in a painter's workflow? I know Kr0n uses it as an edgy tumblr-esque attempt at hiding drawing mistakes, but I could see someone (that actually knows what they're doing) using it as an alternative to blur filters;

Like instead of using a Gaussian blur preset to blur your edges you could just take the red channel and shift it by 0.25% or something creative like that.

Or is it safer to just avoid it altogether?
