I have no idea why I didn't try this before.

Try this: http://www.sharecg.com/v/30625/Poser/HAIR-Colours-CREATOR---Poser

The Hair Color Creator by Abacus3d.  Basically, it works in the materials room making shader adjustments.  There are TONS of presets included as well for all sorts of effects.

You sure you're talking about the right product? The image on that page indicates it's for tweaking textures in Photoshop, not for doing stuff in the material room....
