The only two I'm aware of are and

The others that I know of are a pink/purple mix (like or the for example) and aren't really pink. It'd be nice to have some more pink eye colors out there for pink HA customs.

Have to admit that I giggled at the thread title a bit, but: I don't think more "unusual" eye colors would be bad. Could be a whole line of various non-natural colors.

I also think it would be cool to have some kind of hex-selected eyes, but I could see that being next to impossible to make work.

I honestly thought from the thread title you wanted items that replicated pink eye which is... kind of weird, but hey whatever.

I wouldn't mind having more eye items, but I don't want to limit them to just pink.
