According to the Maliki school of thought, does the persistence of soap residue or its color in the washing machine water, after the removal of the impure substance itself and washing and wringing the garment three times, affect its purity?

According to the Maliki school, semen is ritually impure. Clothes stained with it are purified by washing until the impurity is removed or its removal is predominantly presumed, and the rinse water from the garment becomes unchanged by the semen. Your action is sufficient for purifying the garment, and there is no need to use soap or wring it out if the impurity is removed without them. The persistence of the soap's color in the rinse water does not cause any harm. Sheikh Al-Khurashi mentioned that purifying a place involves removing the substance of the impurity and the discernible taste, color, and odor thereof. As for the predominant view, semen is pure, although washing it is preferable.
