Rich, it appears that you are using a flash to take the pictures. If you can avoid the flash, you'll get more natural colours. I do a lot of close up photos on the centre table in my shop, under a lot of florescent lighting, without a flash. The background has to be something that absorbs the light, rather than reflects it. Your lace tablecloth might be fine, since it has a great broken texture, much like the mountain goat hide I use. But the flash has to go. With today's digital cameras, you shouldn't need it.
Bill Shipman did a great explanation on picture taking...he uses outside lighting on a dull day, so shadows are soft, and natural colour is not overpowered by too much light. Give that a try. If you don't like the pics, delete them. If you do, congratulations!
