The developer of Color Tools added 2 flow cards to be used in advanced flows. That way the converted values can be used right away (without parsing it via an event). Nice service @Shakesbeard 
So this is my advanced flow now:
Upper part is for always updating light color values (even if light is not on, so when switching light on, itās in correct light color immediately)
Lower part is for adjusting brightness when light is on, or when light is switched on. (Notice I use dim level of circadian light zone device, because the trigger cards for switching light on donāt have the local tag for brightness coming from āCircadian values changedā).
