I really do love this theme but in the demo you can choose the color of the product before ordering. I already adding the colors as attributes but they do not show up to the client when ordering so I never know what color the client has ordered. Simply put it does not look like your demo there are no color swatches for products.
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.
