Hello, Abbdul Rahman,
Thank you for purchasing our theme and for reaching out to our support center.
To make changes to the product gallery so that you can choose color only without having to choose color and size together, we have created a video tutorial on our test site. Please watch the video in its entirety and follow the steps outlined. https://www.veed.io/view/cd3ff42d-1535-4644-bcaf-90e4de216e05?sharingWidget=true&panel=share
We appreciate your business and thank you for your interest in our products.
Best Regards,
8Theme’s Team
