Why do jupiter and saturn have no blue methane cloud tops?

Temperatures on Jupiter and Saturn are much too high for methane to condense compared to Uranus.

However, the atmosphere of Uranus is too below par recognized for it to be sure whether the clouds there really consist of methane.

your answer is, orbit around the nucleus

that would be because of both gravity and friction. so     c
