Color ideas for the next’n?

I keep seeing a vid on Pinterest of someone using watercolors to paint an eye like this and it looked cool. I kept putting off trying to do it myself because I hate doing eyelashes (I draw eyes a lot but I don’t even attempt lashes most of the time) and that’s one of the main features in this one lmao. I used colored pencils instead and I have room to do one more so ima try to get the lashes right.

Any color combo ideas?
