Yes, but you haven't gone far enough. Each colour at a gradient node should be customizable through an expression language (like in MathMap), so instead of gradients like 'Tube_Red', there would just be 'Tube'. The highlight for 'Tube' could be 'hsv(fg.h,sqr(fg.s),sqrt(fg.v))', the shadow edge could be 'rgb(fg.r/2,fg.g/2,fg.b/2)', and the deepest shadow could be 'bg'. Then you set the FG and BG colour and get a tube gradient based on those two colours. (Note that my sample expressions think of colour value on the range 0.0-1.0 so sqr() makes a value smaller and sqrt() makes it bigger.) Just an idea :) Tom -- -- Tom Rathborne tomr@xxxxxxxxxxxx -- http://www.aceldama.com/~tomr/ -- "I seem to be having tremendous difficulty with my life-style."
