I've setup a feature and variation as color , it look good on product admin page , filter of catalog but not in product detail page (it just shows the name of it if I check as Text Label).
How can I show the colors in product detail page instead of its label , like filters of product lists !!? (without code modification)
You cannot make it like that without modifications in code. A partial solution is to use feature style "Images" instead of "Text labels", and set colorful pictures (for example, different color models of controllers) as main images of variations.
We can also make a small add-on for your store that will color those labels. If you'd be interested, contact with us through personal messenger.
