Bizarre glitch

[SpiralVortex]

OK so some time ago I'd mentioned that a few fractals were rendering in color, then essentialy displaying in black-and- white. Here's an example.

When you render it, you'll likely find that it starts out in bright colors, but most of them disappear when the rendering is finished::


Does anyone have an explanation for this?

I know people hate to hear this, but ...

It's not a glitch or a bug at all, but actually a feature!  The program is behaving normally.

What you are seeing is very subtle colors being lost in the shadow pass of the rendering.  To bring them back just go to the lighting tab and under "Ambient" slide the Ambient Shadow slider down until you reach the level of color you want.  You can even turn off ambient shadows all together in the post process window if you don't want any at all  

Hope that helps.

Say, SpiralVortex... I can't help you with the problem you asked about explicitly.
But I tweaked the parameters you posted and maybe that would help.
Anyway, the scene is somewhat darker..
