Almost everyone would tell you to stay away from mixed lighting and they are generally correct. But when you understand light better, you can actually produce some spectacular colors, just by mixing light of different temperature. In the photo below, 4 different light sources have been used. On the camera right, there was a big screen monitor producing a light of about 5000 degree K. On the top, there was a ceiling lamp of about 3000K. On the left, there was a black light, with a light of about 10,000 K and in the background, the light source was about 3000K. The Photograph was exposed for the light coming from the Monitor. This is why the blue colors on the neck of this Water Dragon exposed more correctly. But on the top of the head and body, we have intensified the warmer colors with about 2,000 degrees shifting to the warmer side. In the back, the temperature difference due to Light fall off, is even more than 2,000 degrees and this is why it is even more exaggerated. On the left however, we have a temperature difference of about 5,000, shifting to the blue side, coming from the black light. I like the results and again, all done with no photoshop tricks
