Wow Ronald ! I had to look up the term as I was totally clueless about Zorn Pallete, after noticing first that Anders Zorn shares a birthday with me and year ending in 60 as well (18 February 1860, I noticed the amazing paintings he achieved with just a few colors! Thanks for sharing that Robert!
My thoughts is that sometimes less is more, I have to say that I like working with basic elements and it's something I strive for in my own art work. Lately it's been steel and when I go and purchase it I just buy a few sizes and types and work that into my sculptures.
It's amazing what the human mind can do when not forced to think about all the external choices available and works with a "limited Focus" Such is the case with the painting of Anders Zorn. Limitations only exist in the mind and are also over come by the mind.
When I was working on my MFA I spent the first year and a half working with a very limited palette. Eventually I gave into my tendency to use a much wider more intuitive palette but think I learned a lot by forcing myself to paint with major color limitations. If anyone cares I have two works on this site from this era. Page four of my work "Spot" and Ritualistic Dreaming" are the best examples.
