I've recently put together a set of 16 Colorful HDRI Light probes.

I used Apophysis Fractal generator for the image resource. They're all colorful for mood style renders, as you can see inthe examples. I Originally made them to use in Bryce which is what all these test renders are from.

Included are the examples and menu that I'm posting in this thread.

Enjoy
