How to file a helpful issue

The problem you're addressing (if any)

Qube name label colors in Qubes OS Updater intro page is currently hard-coded in CSS and Python. If users create their custom labels via community tools or by invoking admin.label.Create API call and provide their XDG Icons, it will not show properly in GUI updater (all other GUI widgets are fine). The problem is only with light themes.

The solution you'd like

A simple easy fix would be setting black label text for light themes and white label text for dark themes only for user defined custom labels. This is a nice compromise. It will look like this:

The value to a user, and who that user might be

Users who are using custom scripts to create their own custom label will be able to use the GUI updater with the light themes. This is just two lines of CSS (I will submit patch shortly)
