changing circle size and color/other language issues

[Melkor6000]

Hi all
Nice site you have here, and nice program too

I just had a quick question: does anyone know how to fade one color into another. I want to fade a black circle concentrically into an orange one. Can I do this with coding or do I have to make smaller circles with progressively lower brightnesses?

Also, I am unfamiliar with the language and syntax, is there a reference aside from the reference card, which to me is less useful, given my lack of skill with the language. Or would it be just as productive to look at other people's posted code and figure out what it does?

Thanks in advance

You can find more extensive documentation on the wiki.

Context Free does not have color gradients. You have to create color gradients using smaller circles. If you find the hue shifting past orange to yellow or green then you can use the hue target feature to peg the hue change to 30. Initially you set the hue target using this adjustment |hue 30, then you fade the hue toward the hue target like so: hue 0.1|
