What color is the water of the rivers of Paradise, and is the water of Al-Kawthar, which is whiter than milk, the same color as the rest of the rivers?

The Sunnah (definition) mentions that the water of Al-Kawthar is whiter than milk and whiter than snow, and that the water of the Prophet's Hawd (basin) is whiter than milk. In Paradise, there are rivers of milk, and rivers of wine, which are described in the Quran as: "{white, delicious to those who drink}." Some exegetes have interpreted "white" as a description of the wine itself, while others said it describes the vessel. As for the color of all the rivers in Paradise, there are no texts clarifying this, and the details of the delights of Paradise are part of the unseen, known only through revelation.
