@Ulanbek thanks!
@jthomas thanks for the screenshot! I agree with you that the color settings seem to be for the icon only and this is why it doesn’t take affect when no icon is selected. However, feel free to create a feature request on jira.dhis2.org and maybe @Ulanbek as well as other community members can add their votes!
I think your other option is to use the styles.css but for me I’ve not been able to make it work UI Customization (style.css) not taking effect?
