No, I colour match my cages too.
Biscotti is blue, Java is green (and purple), Chai is purple, Darissa will be blue, boys are Blue (with a few random rainbows). My two extra bins (for an unruly sibling) are green and blue. My two large baby bins are purple and blue.
I like purple. And blue. Can you tell? Love the sputnik! I want one... wonder if they'll ship...
