Temporary Hair Dye that will last ONLY a week?

I'm going on a week vacation and i wanted to dye my hair a crazy color. The thing is i can't have that color when i get back because of my job, so i need it to come out easy and fast but not too fast, so that i can enjoy it. Also, my hair is already dyed an auburn color but it was done months ago, but of course is still there.

Plus, i will be going in numerous pools on my vacation.

Is there anything that will work for such conditions?

Thank You

You can use Colorpulse by Loreal. It lasts 8-10 washes. Be warned, every time you wash your hair, they dye will get all over your towel! Its fun for a little change. Good luck. Have fun!
