I decided the swirl under the hand would probably work so used my vector app Skribl to create an image. I played with different colour combinations and decided it was pretty possible to choose the ‘best’ one because it all depends on context. If I had a particular situation to cater for then a particular colour combination might be right. I think the symbol works. I’m actually quite surprised at what I’ve produced for this exericise, and I’ve enjoyed it much more than I thought I would. It was a challenge to come up with ideas but stimulating to do so.
