Do you mean selecting the colors with the colored squared in stead of a drop down select?
You must do it manual. Go to
- Catalog -> Attributes and Features
Edit on the Attribute tab the color attribute. Set attribute type to "color or texture", if it's not. Save.
View the values of the attribute. Edit the ones without a color/texture assigned (or incorrect collor/texture) and assign one. (Color field or upload a texture in the field).
From the combination upload you cannot assign the color/texture to a attribute value. You could override /classes/AdminImportController.php to allow for a third an a forth parameter:
- Value (Value:Position:ColorCode:TextureFileURL)*
or make a change request at Prestashop for it.
For what it is worth. I do no use color types for attribute's. I use a drop down with the commercial color name like "Urban Kaki" or alike. I have my customers also fill a a comma seperated list of primary colors, uniformly named, that the product contains and create a color feature (add them in product.csv) with those colors as values, so customers can search and filter on color properties, but pick the color besed upon the commercial name.
