trips API text color

[GerdC]

I'm playing around with the Motis 2 trips openapi.

Sometimes, it returns a routeColor, which is nice to give markers a color as demonstrated on https://europe.motis-project.de.

I'd like to propose to also return a textColor property, which should be available whenever a routeColor is available.

In the default Motis2 UI, the missing text color isn't obvious, as the rendered vehicle markers contain no textual clue about the route or mode.

As a user, I don't like to play memory on maps.

I agree, this can be added. Feel free to open a PR if you need it urgently.

The change appears to be easy at first glance, but Motis doesn't use one of the languages I'm familiar with, so I shouldn't do this, sorry.

Isn't this what routeTextColor provides already (if set in GTFS)?

Could be added here also:

motis/openapi.yaml

Lines 1141 to 1142 in d773eac

	routeColor:
	type: string

(for the trips displayed on the map, e.g. if you want to write the name on the map)

Code could be here

motis/src/railviz.cc

Line 377 in 42de676

to_str(from.get_route_color(nigiri::event_type::kDep).color_),

probably something like
to_str(from.get_route_color(nigiri::event_type::kDep).text_color_)

Yes, this would be the code change. Additionally the openapi.yml spec needs to be adjusted.
