Four of the characters in this play are the wind.
This presents a problem you may remember from the Disney film Pochahontas – namely, can you paint with all the colours of the wind? If so, what are those colours? Because you can’t really see the wind, can you. Traditionally the main visual indicator of the phenomenon is a trail of destruction. My first thought, then, is things being blown by it.

If you have a more imaginative way of doing this, please leave a comment…

Do the four winds need to be visually distinctive from each other in some way, or are they mostly interchangeable? You could pick color palettes based on the types of settings those winds would be found in — a gentle breeze might have a tropical, warm blue; harsh winter winds are silver and pale blue; the heavy winds that bring in the often-stagnant spring storms clouds are heavy and purple, charcoal or black, whereas the the sleepy winds that push around those brief summer torrents are heavy but perhaps dappled with the oranges and purples that trail behind them in the skies. You may also want to consider that idea of movement and make it a dynamic part of the set or costume — fluttery strips of light silk or chiffon that amplify every movement around them. Maybe subtlety is the key, here…if the words and actions of the winds will inform everyone that they’re the winds, maybe the costumes only need to hint at that with flowy fabrics and movement and can devote other elements (color, shape, etc) to developing the personification that each individual wind character takes on in the play? (Does that make sense? lol)

All excellent thoughts, thank you! I think the winds will be played by people in the actual play, but in terms of promo art I can be as conceptual as I want I think… I will have a play with some of these ideas over the next day or two!
