Add shape as a variant instead of color in Shopify.

Hi, we are developing a store and need the following variants:

Color

Size

Shape

Is there any theme which supports this with a quick add button?

To be more specific:

Hi, I have a peculiar requirement for the store i am developing. Its a home furnishing store . Ex. Table Mats are a product.
It has following variables:
1. Shape: Round, Rectangle, Square, Oval
2. Qty/Batch/Set Of: 4's, 6's, 8's, 12s
3. Color: Red, Blue, Green, Yellow
4. Type: Floral, Modern

How will all this show up on the thumbnail on the home page without cluttering the entire product thumbnail and it should have a quick add option. Any themes recommended?
