Hello,
First of all thanks for choosing our Theme, we are glad to be you in WoodMart WordPress family :-)
.
As your color swatches not shown on your products.You need to make sure that your catalog mode is disabled form the Theme Settings >> Shop >> CATALOG MODE.
And make sure that you choose your product as variable product and from the attribute option “used for variations” option must be checked and variations must be created.

Just follow the above steps this will surely fix the issue.
Best Regards.
