What is the colour of the wind in Cape Town?

Does the wind have a colour, or does the wind take on the colour around him?

I think in Cape Town we have a lot of experience in the wind. After all our wind has a name, the Cape Doctor. Why? because the South Easter blows all the pollution and dirt away. When you walk in Cape Town on a windy day, you could say the wind is brown, because it grabs all the sand, dust etc. On a rainy day in Cape Town you could think the wind is grey, because people’s mood are grey and the clouds cover the blue sky, so you just see grey. On a beautiful summers day in Cape Town the wind is orange. The Sun is shining a beautiful shades of orange and yellow.. On this day the wind takes on the colour of the sun and blows against the slopes of Table Mountain.

Do you know the story of Van Hinks and the Devil that sits and smokes on Table Mountain. One day van Hinks and the Devil started an argument. They argued about who can create the biggest cloud of smoke. The competition between them is still continuing, and that is why when the wind blows and you see a blanket of clouds blowing over the top of Table Mountain, it is the Devil and van Hinks smoking and trying to blow the biggest cloud of smoke. On these days the Wind is white.

The wind can take on any colour, almost like a cameleon, but what is the real colour of the wind, is it necessary to know?
