I haven't done a rainbow ina couple of years, and I quite liked how this one turned out. I could've devoted more space to the orange, but I was afraid that it would swallow the yellow,
The red and yellow were Truly Red and Neon Yellow and they were blended together to form the orange. The green was about equal parts Electric Lizard and UV Turquoise. The Blue was about 1:3:1 Flamingo Pink, UV Turquoise, and Emerald. The Purple was equal parts Flamingo Pink and UV Turquoise.
Another thing I did with my hair about a month ago. I added Sirens song to my side and front fringe and electric lizard over the rest of the colored side of my head >·< and look, I was actually in the sunlight xD
My aurora hair from a couple months ago left large amounts of blue residue in my hair that I haven't had much luck fading out. I really didn't want to miss out on my usual Christmas hair, so improvised with my canvas, using the blue tones of enchanted forest to create a gradient from red to green that shouldn't cause any ugly bleeding when washing. Considering how blue my hair was underneath this, I'm pleasantly surprised at the turn out.
Also, somewhat of a length update - accidentally sitting on my hair has started to happen frequently.
