Random suggestion: filament color validation in MMU_CHECK_GATE

[k1-801]

HappyHare receives filament colors that are later displayed in the UI.
A reasonable continuation would be adding filament color validation for the gates.
There are a few options of arduino-compadible color sensors (TCS3200 and alike) that can be integrated into the selector (somewhere after the encoder), which can provide a reading on the filament color, that can be compared to the color provided by the slicer. The reading obviously won't be accurate, so a tolerance (possibly, a WIDE tolerance) is necessary.

It should be possible to bypass the check for transparent/rainbow/2-colored filaments, etc.

It is an absolutely random idea, but, theoretically, this kind of check can save some headache if the loading order is incorrect.

Sounds like a wonderful and fun project.... but not something I have the energy for at the moment. Note that there is a new "automap" function that you can set to be color. So long as the gate map is accurate, then HH can automap the slicer tools to the correct gate...
