The answer to your question is an opinion, so there is no wrong answer. However, I prefer black hair and bright blue eyes. i think that light brown hair or blonde with brown eyes is prettyy, or black hair with green! I think blonde is really pretty with brown, green or grey eyes.
This is absolutely an opinion question and can not be honestly or logically answered.
For men, women. For women, a hair brush!
