A forum with many categories and subcategories, those requiring admin to prepare and setup many category colors which work well together
For example, my setup has 20 categories and it is one such a case where I would be happy to see it improved.
It is currently very difficult for an administrator to manage a long list of colors because I cannot see the actual colors. This also makes drag-n-drop function less useful because I do not know how to reorder colors if I do not see the colors.
Make a bold line of every color tag have that specific color:
On the example srceenshot a 7px border-bottom CSS rule is applied to
LI HTML elements, e.g.:
border-bottom: 7px solid #95f6db;
