If I had to pick the most dominant color for my eyes it would be green, but they're multi-colored. Blue outer rings, green, amber, hazel irises. Light brown hair with more salt and pepper temples each year.
For what hair color I find attractive on a woman? I don't have a preference. I have dated women who have had blond, light blond, brown, dark brown, fiery natural ginger and black. All were beautiful overall.
