temporary hair dye

[topaz]

I started to ask the Internet this, but then I realized that my friends are actually way more awesome than the Internet:

How well do temporary hair dyes work? Do they wash out right away? Do they produce bright and vivid colors? Which brands are best?

ETA: this is a one-day thing, so super-temporary dye shampoos and the like are potentially fine.

If we were to apply more than one color--say, a mohawk with colored sides--is that likely to be way too complicated for an amateur to attempt on their first try? Would we want to use a semipermanent dye for that, rather than the totally temporary ones?

If you're going for a very temporarily colored mohawk, try aquarelle crayons. The kind you can also use as face paints. You'll get a stiffening effect as well as color.

Both Manic Panic and Special Effects are considered semi permanent. I dyed my hair green with both Manic Panic and Special Effects. The color fades on me but never really washes out. When I needed Soccer Mom hair, I colored over the green hair with a deep chocolate brown, but in some lights, green highlights still show through.

Another option for very temporary is food color.
