I've created a program which creates a fractal based on mandelbrot set .... Currently, for those interested, you can find it here: http://s147645075.websitehome.co.uk/
The colours within the fractal are dependent on an image which I've created. The image is of 256 pixels in height, and just 1 pixel wide. From top to bottom, this image is loaded into a Color array, which is then used alongside the algorithm to produce the image ...
Now, this image (colour sequence) I'm creating is basically a load of linear-gradients of multiple colours - which I'm producing using PhotoShop.
However, while I can produce some reasonably snazzy sequences (i.e., ones which result in a snazzy fractal), I'm just guessing what should be where, etc, and quite often, the result is crap.
So, basically, I'm wondering if there's some algorithm to produce a decent colour sequence? Like the multi-coloured fractals that I see so many of in Google Images: has a known algorithm been used to produce those colours?
It all works too well to be random ... :)
(I'm aware that the number of iterations also plays it's part in the final effect)
