I have had a little inspect of the suggested programmes to support colour work. The one I found immediately useful was Adobe colour CC . This programme is brilliant in some ways. I like that you can choose a theme for the colour selection; colourful, bright,muted, deep, dark or custom. I can see that it is useful to get an overall idea of the colour palette of an image. I may use it to help with the yarn wrap and collage exercises.
All distracting to play with and hyperlinked so that I don’t forget them. I will revisit to update soon.
