Juliet Docherty, a fabulous artist and educator whom I recently spent the day with on a colour theory course reminded me of this app. I had down loaded a free check it out version previously but not spent much time with it. I have purchased the full version now, which gives you the full text of the book it’s based on plus some really cool interactive colour plates you can move colour sections about on and the ability to make your own colour plates using his clever formats and save them as an image or vector file.
It is fabulous teaching tool for your own colour theory adventures – highly recommended.
