# Colour Scheme The colour scheme for the Wallboard app gives you the flexibility to configure the three traffic light colours, Red, Amber, and Green, to suit. These colours are used in the Monitor app and the Supervisor app as well, where they can be configured for each User. The Wallboard app, which is not User specific, takes the colour scheme of the designated System User, whoever that may be. To change these colours you must change the System User colour scheme, which can be done in the Administrator app. See Changing User Colours for details.
