Brian beat me to it. I've run into the same problems in the past with strobes. Elinchrome's worked well, AB's not so much. I found the best results using large soft boxes and tungsten lights. We did projects for two museums this way. Two Chimera mediums with hot lights. Shooting needed to be quick as the artwork couldn't withstand a hot room.
If you go this route a trick with smaller artwork is to only use a single soft box for the lighting. Position at an angle and use a flag between the light and artwork to feather the light so it is even across the field. If you are shooting tethered, move a white (or gray card) around the frame and adjust the light and flag until everything reads within 1 L*.
That said, Lou isn't seeing wildly inaccurate colors - contrast being the problem at hand. Light quality is likely a secondary issue. Ben's suggestions of eliminating reflected glare and checking with a mirror are right on. I suspect a shot of the mirror will show much unwanted light.
As one of the constraints was using equipment at hand, we're working with the AB strobes. If you have softboxes or diffusers, I'd try them. Otherwise, see if mounting the lights at opposing 45 degree angles to the vertical and cross polarizing may help.
Best of luck,
Ethan
