On my website, We sell thread. The product is the thread line and the the colors are set up as attributes. Currently, the attributes are sorted according to the the color number. I would like to present the attributes arranged in the sequence of the rainbow. I am not sure how to do this. I thought about making a duplicate of the product and changing the sort order of the attributes. Where would I change the sort of of the attributes for one specific product without effecting the sort order of the other product. TIA Tom
