When it's about to rain, clouds darken in colour because the water vapour is clumping together into raindrops, leaving larger spaces between drops of water. You can determine all these by the colour of clouds because the colour of the clouds, the weather.

The funny thing is that immediately we see black or gray clouds, we draw conclusion that it's about to rain. But it is not all the time that when we see black or gray clouds, it's about to rain.
