Colour scenes can be set for DT8 devices in the cloud. After you have created scenes for the control systems that the devices are on then you can find the Colour scene assignment tab under the Groups & scenes panel in grid view.
This view is very similar to the regular scene assignment but instead of arc levels, colour values are used. The arc level for the regular scene assignment will be used for the intensity part of the colour value. Scenes that are editable will have a white background. If they are grey then that means that a scene name has not been created on the control system for a group that the device is assigned to.
Clicking on an editable scene value will open a colour picker based on what type lock is set in the colour control view for the device. The colour picker is the same one that is used in the colour control view for the power on colour and system failure colour. You can either disable the colour so that scene will not go to any colour and just an intensity when recalled or set it to a colour based on the type lock for the colour control.
