I'm a big fan of listening to talk radio while I work in my studio and one of my favorites is a show called Radiolab. Radiolab is a great show that focuses on exploring the world around us. They have a very unique way of putting a show together. Lots of amazing sound design. I can really do this show justice describing it. I'm posting this because one of their recent shows was something every painter should listen to. They covered the topic of Color. You can go to their website or iTunes and find their entire catalog. IT IS FASCINATING!!! Take a listen:
It you want to have more fun after listening to this try this: Farnsworth Color Test. This directly relates to one of the segments in the show. I scored a 4 the first time. I got annoyed with that and took it again, taking more time, and got a 0!
