Hi @orlane_azogui
After defining the attributes like your colors, all of them are listed in the widget that you sent via the screenshot.
The second step is defining the code of the color right in the widget.
Watch THIS
So, for making available that color in your filter you need to enter the code of the color.
And also remember in the page that you are using the filter, if you don’t have a product in that color, you will not see that in your filter.
And this is the same story for color, size, volume and etc.
For finding the right code for your color I recommend this Link or using the widget color picker.
However you can find them directly by searching them on the Google.
Good Luck. 🙂
