I did a search to see if this had ever been suggested, but did not find anything, so here goes:
For those color hounds like myself, have you thought about offering a swatch kit of the different fabrics & colors, for a price of course? Knitting companies & furniture stores offer them routinely. It would be so helpful when trying to decide between plum/olive vs. plum/wasabi, or punch/steel vs. punch/navy, etc., etc.
Also, turquoise would be a great addition to your stable of colors - it would be great with cocoa, olive, navy, cork, sand, steel, black . . .
