Issue Summary

After upgrading Confluence from 7.13.x to 7.19.8 (the latest LTS version as of now), the customized color scheme can't be seen on the Login screen.

This is reproducible on Data Center: yes

Steps to Reproduce

1. Install Confluence 7.13.x
2. Change the 'Color Scheme' for the top bar
3. Log out from Confluence to see the color scheme still in place on the login screen
4. Stop Confluence
5. Upgrade to Confluence 7.19.8
6. When the upgrade completes and the application is up and running, navigate to the login screen

The same behavior applies to the 8.2.2 version (the latest released version as of now) and I am sharing screenshots from this version.

Expected Results

We should see the same color scheme applied to the site on the Login screen.

Actual Results

We are getting the default (blue) Login screen but after logging in, the customized color scheme can be observable:

After logging in:

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
