This post is inspired by Maggie Latham and her fantastic series of posts on colour. (The link to the first post is here but do make sure to read the other posts in what an interesting, well researched and very well presented series. I can't recommend them enough, she is so generous with her knowledge.)
I love colour mixing charts, or as I think of them, recipe pages. If there is left over paint on the palette or sometimes just for the joy of it I'll start playing with mixing the colours. I don't think time spent doing this can ever be wasted and sometimes out of this kind of play unusual and unexpected combinations can be discovered.
The first two images are preparation for a 'Mixing Greens in Watercolour' class that I held a few years ago. Although using colours that I had used lots of times before I remember getting very excited about forgotten combinations.
There are now only three days left to post a comment here to be entered in my blogoversary painting giveaway - don't be shy.... :o)
