Solder mask is there, yes to protect the board from whatever may be in the environment, corrosion etc, but also to isolate the signals on the tracks so that they do not get shorted etc.
At different altitudes it has different effects on preventing flashover between tracks too.

I have had boards that are Grren, Red, Black, Blue, Yellow, White....
