@Cheerlights to various RGB devices
This flow shows an example of how to parse a Twitter stream for the @Cheerlights supported colours and creates an output for each one found.
These are then passed to a rate limiting node to allow each colour to be shown in turn. A trigger node is then used to add "black" to turn off the LEDs after 4 minutes if not re-triggered beforehand.
The colour name to r,g,b and hex values can be used to drive other RGB LED type devices as appropriate.
