Site's Appearance (UTM Minor)
As of the 2017-09-14 update, most sites will be using the UTM Minor theme. Within the appearance settings you can change the colour scheme of this theme. There are 5 colour schemes to choose from.
Note: Selecting a colour scheme from the dropdown will display a preview image of the selected scheme. This will not take effect on your site until the settings are saved.
Settings will only take effect after clicking on the Save Configuration button.
