At a company I used to work, a co-worker had two different eye colors.........................
Someone I used to work with had blew eyes. One blew East, one blew West. Kinda like this guy:
I had a friend, in high school, who had the same thing. She wore a brown contact, in the blue eye, and blue contact in the brown eye.
It didn’t even out the two colors, but, it did make it less noticable.
