Make bus route numbers easier to read #4
Description
A lot of them are black text on very dark-coloured backgrounds. I tried to add some light text-shadow to help with that, but it's still kind of hard to read.
I tried making some of them have white foreground text and some black, but didn't like how that looked. So I think we may want to just figure out how to dynamically lighten the background colour. I have a feeling that's what Google Transit does? It has to be subtle though. The colours should still be recognizable to anyone used to the ones shown by Google Transit.
Also on a related note, some of the arrows are really hard to see because they are so light. So it'd be nice to dynamically darken those in the same way.
