Look Me In The Eyeball!

Thumbelina has the most beautiful eye color. It's not blue, but it's not green, it's a mixture of the two that leaves me staring at them in wonder. Alice and I have brown eyes. Mine are darker, almost black, though many people tell me they turn orange when I get really angry. (that would be the hell fire, I guess)

Thumbelina's look almost as if the color is moving. I don't know where the color came from. It has to be some far back gene that both her father and I have, but we have no living or known relatives that have it.
