Adventures in funky hair, take two

The first experiment in hair color, a "peekaboo" burgundy color that wound up being almost invisible (too small a portion of hair colored, although the color itself was great) has been in the rear view mirror a while, and I decided I was going to take another stab at putting a funky color in. I went back to the hair college, which has actually been pretty decent for me, and opted to get a stripe of a vivid dark purple put in. My student, a very nice girl who nonetheless worked on me like she was working on disarming a bomb - one wrong wire cut and the whole thing explodes, so better call the manager over to check every three minutes - completed the process and sent me on my way. I had spent three hours in the chair at this point, and was starving, so I opted to let my hair dry naturally. "Come back if the color isn't right!" chirped my stylist.

Uh.

The color isn't right. Instead of a vivid purple, it's a pale, pale, might-as-well-be-grey purple, and even with the top of my hair pulled back to show it off, I suspect it may not even register as a funky hair color. So I'm not sure what to do. Go back and see if they can brighten it? Forget it and never experiment with this sort of thing anymore, since clearly my hair is dark enough to really fight being colored? Get a sharpie and start coloring?

Forty bucks. Blah. Maybe I should go back, but it's always such a pain and things are busy right now.
