Hello,
To handle color options for your product, the best approach is to use a variable product with a color attribute:
Make sure your product is set to “Variable product” instead of “Simple product”.
Navigate to Products > Attributes, then create an attribute called “Color” (or similar) and assign color values such as “Red”, “Blue”, “Black”.
In the product edit page > Variations > Add variations from all attributes, generate the variations so each color term becomes a selectable option.
This way, each color becomes a separate variation, and you can display the Color & Size Guide (created via Size Guides) alongside those options on the product page.
Best Regards
