Has it always been that color? Or did it recently change? Because when vaginal discharge
changes color it is usually because of an underlying infection. Emotional stress, a tampon or foreign body left in the vagina, or ovulation. But to prevent excess discharge, keep your genital area, clean and dry, and do not 'douche' (washing the inside of the vagina with various solvents, such as vinegar, scented soaps etc.) As this can increase chances of infection.
