The idea of the effect of cool warm color combinations has been around for at least 40 to 50 years. I learned about it in the third grade, and I am 51. The colors that you chose, are very close to perfect for presenting the effect. If you would like to see some very wild stuff, you can order a set of chromadepth glasses at the following website.

One word of caution though, it is addictive, and you will never look at anything the same way again.
