What is the colour of the wind?

I may consider it as a serious scientific question, in which case we must first consider "what is wind?".
Wind is the movement of air molecules. Can air molecules have color? If they have color can they have more than one color? Air molecules are colorless. However, air often has other molecules mixed in it (e.g. smoke). These other molecules often have 'color'. Thus, they impart a color to the mixture of air and smoke. If this mixture is 'blowing in the wind', then the air may be perceived to have color.

How high does the sycamore grow, If you cut it down, then you'll never know, And you'll never hear the wolf cry to the blue corn moon, For whether we are white or copper skinned, We need to sing with all the voices of the mountain, We need to paint with all the colors of the wind, All you own is Earth until, You can paint with all the colors of the wind
