Tip: use of colour symmetry

Whilst I must confess to a lack of mathematical rigour in my understanding of this function, what really matters for the artist is the effect. By default, the colour symmetry is 0 for all transforms. It may take any value between -1 and 1. -1 corresonds to "this transform's colour does not contribute". Increasing the value towards 1 has the effect of distributing the entire gradient from around the transform. For high-weight transforms, values closer to 1 give best results:



Here, transform #2 has weight = 30. For this gradient:



For others, experiment! One notable effect is causing colour to begin abruptly at a structural boundary and fade across the structure. Star mandala amulet is a good example of this.
