Is it possible to distinguish between mani and madhiy by color only, keeping in mind that in my case it is discharged involuntarily and is yellow, and it is not feasible for me to purify myself from it always due to water scarcity and lack of time?

The woman's semen is characterized by being thin and yellow, with the scent of palm spathe. It is discharged with pleasure, followed by a decrease in sexual desire. As for madhy (pre-seminal fluid), it is a thin, white, viscous fluid that is discharged when sexual desire is aroused, without pleasure, and is not followed by a decrease in desire. Therefore, the yellow substance that is not discharged with pleasure and is not followed by a decrease in sexual desire is neither semen nor does it necessitate ghusl (definition) (ritual bath), but it does nullify ablution.
