Complementary colors are often used as a set, with one color in the foreground and the other in the background to make it "pop". Blue and Orange are the second set of complementary colors.
Also - KITTIES! Because my friend said so. And naranja is Spanish for orange. Why use that instead? Because I can.
Fonts used - Gautami and Hobo Std Medium (for the name of colors and the kitties)
