How to remove attribute or variant in wordpress woocommerce variable product?

Question

WordPress

There is a variable product on woocommerce, it has 5 fields:
1. type (with one color, with two colors, with three colors)
2. quantity (we are not interested in this)
3. color-1
4. color-2
5 .color -3
Comp. in the variant with one color, the other two should be inactive, or disappear. I have no idea how to do this on woocommerce, because options are made from all attributes.
