Relative humidity. Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapour is required to attain high relative humidity in warm or hot air.

I've seen the same planet colored differently in different photos. Here are the true colors of major planets to the best of my knowledge (spacecraft photos appearing in the media often have false coloration):Mercury: grey; Mercury has practically no atmosphere, so we just see the rocky surface.ere are the true colors of major planets to the best of my knowledge (spacecraft photos appearing in the media often have false coloration): Mercury: grey; Mercury has practically no atmosphere, so we just see the rocky surface.
