Hello,
I saw your product which you shared with us. It contains 3 color swatches and only one display the actual color and other 2 display color name. It seems that you did not select colors for those swatches. You need to make sure that you select the colors for “Color preview for this value” option inside the attribute swatches.

To make the color swatches works in appropriate manner you need to also select different prices from your product edit page >> variations. Also you can check the below documentation for in depth guidance: https://xtemos.com/docs/woodmart/variable-products-swatches/
Best Regards.
