Once a user uploads a part on the Front End (FE), on the right hand side, they are given the option to choose specific parameters.
If the colour depiction is not visible under the material as shown below, this would mean, that there is no thumbnail image uploaded for that colour.
The way to fix this issue, is by going inside Management Console (MC) --> Settings --> Production Parameters. The user should then navigate to the colour in question and add a thumbnail image to it.
Now that the thumbnail image is added, a small icon/circle would appear on the Front End, showing a colour, that corresponds to colour name (in this case Black).
