Style
To access the organization style settings page, go to your organization's homepage and click on Organization Settings in the navigation bar and click on Style.
You'll be able to change the icon on paid plans for your organization here, which is displayed across all organization pages.
You'll also be able to modify your Organization's CSS on paid plans which will apply to all organization pages.
Use your browser's web inspector to view class names, IDs, or elements, and then stylize them to your liking.
For example, if you wanted to change the navigation bar color to red, you could use the following CSS:
#minnit-navbar-nav{background-color: red}
