It would be fun to have colorful lights!
We agree that colorful lights will be fun. And we have plans to add them some time in the near future. They will be lights that you can connect to the microbit that will have every color imagineable. We don't control the design or manufacturing of the microbit itself, but since it is limiting in the number of LEDS it has right now and only 1 color, we will eventually add way more awesomeness to the light lessons.
