3487.0. "FireFox and Colors" by TAV02::MELVYN () Thu Oct 18 1990 12:06

Hi,

I have a customer who is having trouble with on a Firefox with 8 planes.

He claims that some of the color indecies returned from XAllocNamedColor are
rubbish.

Does anybody know if the default visual for the 8 plane system is pseudo or
true color, and are all colors in the X family supported as if it was 
a standard VS3100.

Thanks

Mel

	If the HARDWARE has only 8 planes, the default visual is PseudoColor. If the hardware has 24 planes, the default visual is TrueColor. However, you can still get 8-plane pseudo...it is just not the default. If by garbage, the customer means that the indices are way out of range, that is odd. I don't understand it. However, if the customer means that, say, Loden- green is not really that color, I believe that. Unfortunately, no one has ever standardized anything about these colors, least of all what they should look like. Theoretically, we should use a different set of definitions for each type of hardware, but since there is no real standard to compare against, we don't. They can be changed by defining logicals: see sys$manager:DECW$RGB.COM. Burns
