My client would like to color test a product where we have a B&W line drawing of the product and the respondent can pick colors from a given pallet. The ideal solution would be drag and drop, so that the respondent can "play" with colors to develop their ideal color scheme. The final product could be all 1 color or multiple colors depending on their taste.Is this possible with Qualtrics? If not, does anyone know of another solution that could perhaps be integrated into Qualtrics? Thanks in advance!

It's possible. This is a demo for a colour picker that I created for a client. It deals with charts and sliders, but the idea will be the same.
