We have products with two variables for variations: color and size. When we create a view on the product display we get the unique products. If we create a view with commerce products we get a list of all possible combinations of product sizes and colors.
Now we would like to have a view which shows all products for each color, but not size. So for example:
Colors: Red, Green, Blue
Sizes: 24, 25, 26
Colors: Red, Green, Black
Sizes: 25, 26
Using product display results in:
Product X, Product Y
