I used one fractal formula and camera, and a single click to change the style for each version, then adjusted a value in very tiny amounts to balance the colors in each render so not too much of one color or the other. That part was fast, but each render took about 20 minutes.
I created the fractals starting with the exact colors. The tool is the same as the gradient picker in Photoshop. I picked this fractal because I knew it would let me play with the colors with at least some control although not a lot. Most won't cooperate at all.
