My son's room is in sky blue and lime green, with a lot of animal art. His curtains had a Noah's Ark theme, so stuffed animals worked fine, and he had a pillow with a monkey needlepointed on it.
My first son was pretty random and most of it was blue so I thought green is a really cute color and if i ever have another kid Boy or Girl i have something that can go either way
That's what I did :)
I even painted like a forest on his wall and everything in his room is safari theme. Lions, giraffes, zebras,and monkeys. And light green, it's so cute :)
