Can you help as nothing in the support documentation.
Breathing red is not a standard Device OS color.
Aside from a soldering issue on the LED, the most common cause is insufficient voltage. Since the red component of an RGB LED typically has a lower forward voltage, a supported color like breathing white shows up as breathing red because the green and blue colors aren't lit up. More commonly you get blinking dim red because it's actually a white blink with a brownout reset, but the white shows up as dim red.

Rick - thanks, that's really useful. It gives me something to go on. Maybe - could be added to the documentation?
In the past I've sourced the wrong footprint for my status LED on a custom design and ended up with a number of new LED states. Worth double checking the layout + schematic.
Thanks for the suggestion Eric. There isn't an issue with the operation of the RGB LED otherwise. This is a P2 on a custom board and there is a lot of control of power to peripheral ICs and signalling being combined due to a lack of pins - there are thus some timing issues with the power on under certain scenarios.
