Hi @pawsfurlove,
My recommendation would be to add the various colors as modifiers to the main item, such as Shirt. You can also add a second set of modifiers such as size. However, you might sell 5 shirts, 3 red and 2 blue all you would be able to do it select red and blue but not the number of each color unless you rung them up as separate orders. For example you could choose Shirt -> qty2 -> Blue -> XL and add that to the order then select Shirt -> qty3 -> red -> XL and add. Now you have 5 shirts on your order and receipt.
