I took a color class from Roberta Horton in 1991. She made you work with a color you didn't like -- in my case the color was orange - crayon box orange - UGH! The class was 5 weeks long and I have to say that I hated most of the class, there is nothing worse than working with a color you don't like. I just couldn't see past that ugly color. Finally, she just looked at me and said, there is a whole family of oranges out there: burnt orange, rust, pumpkin orange, etc...
The light bulb finally lit above my head (I'm a slow learner) and from then on I never found a color I didn't like. She opened my eyes to my color prejudice and made me realize that there are many, many colors out there that I do like in orange and every other color under the sun.
When I was a kid and into my 40's my crayon box was just the basic colors. Now that I am in my 60's my crayon box is beyond my wildest dreams.
