Are there different colors of semen? Am I sterile?

My semen is kinda clear but the consistency is the same as others I see. (I'm gay, I have experience in this field) (lol) I was wondering if my semen was clear because I was sterile, (I'm 15, pubescent) or if there are just different shades of it. I've seen a lot of bright white semen and makes me self conscious about my own. Just the other day I saw the most adorable baby boy named Jordan and he would giggle and I would poke his belly and wiggle his toes, and it made me think about children of my own (maybe if I'm wealthy in the future I could have a surrogate child) and makes me worry that I cannot impregnate. Little help to put my mind at ease?
