When using “Color/Select field” on a custom view, you can only choose single-select fields. Adding lookup fields leading to single-select fields would be nice.
My use case:
I have a list of people assigned to groups. The group table has a single-select field named “Color” where each option has its own color.
I want a view showing people colored according to the group they belong to.
In a more simple case, I would use a single-select field named “Group”, where each value would have its own color. But here, as I need to store informations about groups, I need them to have their own table.
