ATI Mach64 colors...
It occurred to me yesterday that the colors on my fine Power Computing 604/150 looked a bit odd. Mostly the Mac face was pinkish, rather than blueish. Upon closer examination and a trip into Photoshop, I discovered that on the RGB sliders, Red is blue and Blue is red. The ATI card has both a standard VGA plug, as well as the 15-pin plug, and the color issues appear regardless of which one is used. (And the 15-pin-to-VGA adapter I used to test works fine on a 7100/66av.) At first I thought that some strange color profile had been set on the OS 8.6 install, but I unplugged the HDD and booted off of a 8.6 CD-ROM and the issue was still present.
Any ideas?

My first guess is a failing video card.
If you have another card, or internal video try using those and see if the problem still persists.
Also you could try resetting the PRAM and /or CUDA switch if your machine has one.
Finally after that I would start looking at the system RAM and swapping in known good modules if you have any and see if the problem is still there.
Also I would strip the machine down to the bare essentials needed to boot it and slowly add hardware back in 1 piece at a time until the problem reappears. It could be that everything just needs to be re-seated in their slots.
