Was going to post a quick SBS on dyeing stuff with Koolaid. As always, I did a quick search to see if the ground had already been plowed (not much sense re-inventing the wheel, is there?) and found this

Great article by Tom Deschaine, very clear and concise instructions, although there's no way I'd tempt the wrath of my wife by using Rit in the microwave. By the way, this works pretty well on dry fly hackle although you're going to want to give it a bit more time to soak in; grizzly dyed Lemon Lime makes a pretty cool (western) green drake/flav hackle.
