How Variant?

Hello,

I have a prouduct which has variants. let's say I have "item A" with a SKU number 123-X4567
where X is a code for color {0=Black, 1=White, 2=Red}

I have used Product Variants so I have it now as:

Item A

Balck 123-(0)4567

Red  123-(1)4567

Blue  123-(2)4567

So far things are OK but I just found this item also can have a tag, where the tag can have colors itself! and when customer orders it he/she might order base on color of item and also color of its tag.

So what I need to understand is to find out how I can declare an item as following:

For Item A:

(Black/White) = means it is black with white tag
(Black/Silver) = meants it is black with silver tag

How can I mimic this in nop-commerce?

Thanks!

I think adding a drop-down control (representing tag color) for each variant would be helpful
but how is this possible in nop-commerce?
