What is the ruling on performing ghusl (ritual bath) and prayer when a cloudy discharge, whose color cannot be clearly distinguished, appears after purity, especially with the existence of a problem in distinguishing color shades?

Al-Kudra (dark-colored discharge): It is a discharge similar to pus or dirty water. If it appears immediately after menstrual bleeding, it is considered part of menstruation. Do not rush until its traces disappear and you see your accustomed sign of purity, which is either complete dryness of the area or the emission of the white discharge (al-qassah al-bayda’), based on the saying of Aisha, may Allah be pleased with her: "Do not rush until you see the white discharge."
