Well, there are such things as facial hair dyes if the colour's too light... would be worth considering if you're really that desperate.
Funny, I was in a debate with myself about facial hair for the last little while. I just can't grow enough of it, even though I really like it. Ended up shaving it all off yesterday after deciding it makes me look far too sloppy and unprofessional, but now I feel naked and ironically it's made me look older all of a sudden (odd, usually the opposite happens when you shave...)
