Has anyone managed to change the colour of the heater control lighting yet?

I have stripped mine down, and the buttons/faces are made of green plastic so changing/painting the LEDs will make no difference.

Does anyone make these in different colours yet?

Is there some scientific way to filter green, so it looks blue?
If I'd been more attentive in primary school instead of making plastacine ****** I would probally know.

 

Come on brainiacs.

Someone must of tried somthing.
