Semen is a cloudy, milky white, although there can be some variation. So it could be slightly off-white, slightly yellow, or a murky, grayish white. It may sometimes be clear. It is usually white. There may be some ethnic variation which may make it slightly off-white, since there might be some shed skin cells in with it.
