Napalm Orange and Nuclear Red
For this, I used Napalm Orange and Nuclear Red. I've done nuclear about 3 times, including this, and what never ceases to amaze me is how bright it comes out. My roots are insane in this picture, because I've left it in for so long. I don't mind the way it's fading at all; the colors are staying in great.
As it fades, you can also begin to see the difference between the red and orange, which in the beginning was really hard.
