Tip: colour distribution

Depending on how you build your fractal, or where the parameter came from originally, chances are that your chosen gradient isn't fully distributed. Fine if you like what you see, but not the best situation for actually selecting a gradient. To remedy, from the menu Flame, Calculate Colors Values - this gives full colour distribution i.e. transform #1 has value 0, transform n has value 1, with transform i (0 < i < n) having value (i - 1)/(n - 1). Obviously, you can pull the sliders to what values you like, but this gives a standard starting point. For alternative colour distributions, I have a script available here - only any use for 4 or more transforms.

The situation is somewhat complicated if one transform possesses the lion's share of the total weight - the colour value of this transform will dominate, sometimes to the point of turning the whole thing duotone. To introduce more colour, use symmetry .
