I recently subscribed to Alisa Burke's online class called "Color Your World" and thought I would share just a few peeks into my journal. I haven't done the "homework" yet but I did go all out on demonstrating the theories in my journal. I chose watercolours as my medium of choice.
My colour knowledge is actually really strong as it is a favourite topic of mine, so while I may not have learned much new, getting the theory down and really reminding myself of it was fantastic. If you are interested in colour, I would recommend this little online, self-paced class.
