Ahhh, this is something I learned in college and have been using rampantly ever since. Everyone keeps asking how to do it.. and now, they know. Thus far, the only real issue I’ve ran into with this method is when the gradient of colour isn’t linear – recreating the colour effects can be a right pain in the butt to get to match without being entirely obvious. That being said… it can be done.

Excellent advice, good sir!
