You may be referring to the ejaculate or the semen here.
Changes in the color of the semen may suggest an underlying infection . Other causes will be a previous trauma , diet and sometimes medications.
Do you experience any change in the color of the semen?
I suggest that you have a consult with a urologist. A urinalysis and urine culture as well as a prostate secretion culture will be able to help rule out an underlying infection. A complete physical examination including a digital rectal examination will be able to help assess any involvement of the prostate.
A prostate infection is something that has to be considered in cases wherein semen color has changed.
Was there any history of previous trauma in the area?
Also, do you have any associated symptoms like problems with sexual response and change in urinary patterns?
