﻿At this point, the colour can be specified, which is set every time the DALI operating devices are switched on. This parameter defines the switch-on colour value separately for each group and each single device.

*Track*: When switching on, the colour value specified last and internally tracked in the "Brightness 0%" state is set. The tracked colour is not influenced by an ETS programming operation or by a bus voltage failure ("no change"). When the bus/mains voltage returns, the colour most recently active before the bus/mains voltage failure is restored. Consequently, this colour is taken into account as a value to be tracked when switching on.

*Preset*: The set colour is set with polarity "activated" when an ON telegram is received by means of the communication objects "Switch - Setting" or "Colour ...  (Switching) - Setting" or when receiving a central telegram with the polarity "activated". In the "RGB individually" or "RGBW individually" colour spaces, only the corresponding colour value (red, green or blue) is evaluated in the parameter when switching on with the objects "Colour ... (Switching)". All other colour values remain unchanged. When a colour is switched on, the gateway always also switches on the brightness in the configured switch-on brightness.

*Memory value (value before the last switch-off)*: When switching on, the colour is set that was active and stored internally before the last switch-off. This memory value is composed of the colour value and the optional white value and is stored in a non-volatile manner in the gateway so that the value is retained after a bus or mains voltage return. After an ETS programming operation, the memory colour value is predefined at "#FFFFFF" and the optional white value at "#FF".
