kind of Solved,Color+ eg. 2 item in stock only show for size A =fail

[Zigma]

Well hello,

I have2 product.

Shirt- size Small and Large- RED colcor
Shirt - Size medium - BLACk color

When choosing size small I can also choose black color. But there is no vblack color for small (but the consumer can choose it because of the red color shirt are in the same catageroy as the black one). Is there a way to limit size small to only one color?

EDIT: Well I solved this by writing SIZE/ COLOR in the attribut and then add the item instead adding color, then adding size etc , much easier doing so
