I "think" I know what you mean.
I'm guessing that all the "items" are the same, therefore the only variant is the colour.
As you need approximately twice as many pictures as you can load, and putting lots of items onto one frame just looks wrong can you perhaps do a half and half on each picture ?
On your main picture choose your most popular or eye catching colour, then for the rest, on drop down, do half the picture (left side of item) in one colour and the other half in another option (right side). A quick explanation to cover yourself for the terminally stupid (who thought the VW Halequin was a single colour option not a selection of all of them, and bought it

) and you should be okay.
I just KNOW that someone on here has the Harlequin and I'm going to get grief for my comment
