I want to customize the color variant, there are only two options for the color variant, it is taken from the image that is entered in the attribute or from the thumbnail, but what I want to ask is if I can make additional input to be able to customize it with the image that I input again when I entry products
Sorry, there is no third way to do it. You can only add the image from the attributes or color. The 3rd option it requires customization.
If you want to add the color instead of the image then you should edit the Attributes >> edit the color >> and add the color swatch: https://ibb.co/5MP0x6R
