A few more shots after the jump!
I wanted the colors to be super bright so I whipped out my MANLY 80-Color Palette which I haven't used in the longest time. While there are 7 colors in a rainbow, I think I used at least 10 to get the colors nicely blended into on another. I skipped the glitter. I figured I'm already pushing it with wearing rainbow eyes to the office.
It wasn't too difficult to do and I like it a lot! Let me know if you'd like a tutorial for this.
Check out the rainbow I spotted while I was at the KL Bird Park. It was gone after 10 minutes of the shot.
