i nominate you for vague problem of the year.

you say that the colors seem altered, which means you MUST have a frame of reference to which you are comparing you blitz program.

come now - you made something like candy designer - surely you know how to make a valid help request!

I've noticed that setting the gamma to 0,0,0, on any computer, gives good results. My downstairs computer is usually very dark when running blitz stuff. But, seting the gamma to 0,0,0 sorts that out. I don't think i've noticed the color thing though...

I'll try.

I had different results with several graphic card. It seems to be not a Blitz bug.
I'll add a gamma brightness control.

@DrakeX
Sorry, I can't take a screenshot of this visual glitch.
It's such a pity. :/

I always put this immediately after Graphics3D to fix a problem on some graphics cards where the brightness is blown out

Also I don't think you're new to this but a while back one of the updates (or maybe this is only a BlitzPlus thing) changed the way it works so that minus values now give strange results (whereas before they were interpreted as 0).
