I made an entire colour wheel of eyes like these. I think I'm going to put them in a pack and upload them.

Transition is from hazel (my shade of hazel anyway, which is more of a green/hazel) to yellow, like a cat or something.
If you would like this personalized to tour eye colour, don't be afraid to note me and ask.
