To be honest, I agree…

Its definitely worth looking into, especially if you later on may want to have transparent glass, 32bpp graphicsfiles will "remember" transparency information, enabling for example colored see-thru glass or glass with a sun-glare, rather than just the "standard" darker glass effect with 8bpp.

That one is still 8bpp actually, Part-3 of the Addition-sets is 32bpp, the first two are 8bpp.

Yes there is, you need to add that as an 8bpp mask-type, with just the colors you want animated/company-color.
Not sure though how to do 32bpp and masks in M4NFO (If I am correct you are coding the stations with that, right?), but there is a bit of information about that in the manual:

Its already very easy to do in "old-school" NFO, so wouldnt be too difficult too in M4NFO.
