Christian,
I've played with Chaoscope for a month or so now, and here's what
little I've seen with Solid rendering:
Background is fairly obvious, but remember that it can have effects
on semi-transparent (thin) solids.
Ambient seems to have the strongest effect on overall color. This
makes sense, as ambient lights in 3D generally are the lights that
give an overall color. They are usually somewhat vague (not like a
spotlight), so they tint everything.
Diffuse lights are similar, but in Chaoscope, the Diffuse value seems
to have a softer effect than Ambient.
As you've noted, these two (Ambient and Diffuse) will be the main
color tuners. I usually leave Ambient fairly dark since its effect
is stronger, and tune with Diffuse.
Secondary is a light that appears to enter from the right side, and
behaves more like a spotlight, with strong directional effects.
That's where the shadows are generated from, too, so far as I can
tell. As such, the shadow color is affected by the Secondary light
color, but it's a relatively subtle effect compared to Ambient and
Diffuse. Also, it tends to have a slight golden color shift from
whatever value you give it. I'm not sure of a good way to compensate
for that, so plan accordingly.
Specular doesn't seem to have much effect because it's very very
subtle. It really just tints the highlights slightly (the specular
part of the lighting), so it may not even be visible in some
renders. Most of the time, though, it's just a tint in the
highlights. I see it most in some Unravel renders where there's a
strong set of planar surfaces (looking like some sort of spongy
stone). Also, a nice simple Chaotic Flow loop will let you see the
subtle tinting.
You could also turn the other colors to black to see what any one
light does. That's especially true for Specular; you can see how
little it does... but it does do something. It also makes for some
interesting shapes.
So, I hope that helps! I could have been a little less wordy, but I
hope it makes sense nevertheless. Also, if you hear any other tips,
would you please forward them to me? I'd like to hear what others
(including you) have come across when rendering solids.
Thanks,
Taylor

Hi Chaoscope Users,
is there somebody out there who can give me a short description on
how the 5 color values within a solid render will work together?
Is it right that for example Ambient and Diffuse will result in a
mixery of both values?
F. e. Ambient = red, Diffuse = blue -> result = pink?
What is with Secondary?
What is with Specular? I never see that something changes, when I
change this value.
Any tips are appreciately welcome.
Best regards
Christian
