Berlin metro line U6 - incorrect color on Subway layer

[Hallilogod]

Description
Berlin metro line U6 is displaying an incorrect color on the subway layer in Organic Maps.

Steps to reproduce

1. Open Organic Maps.
2. Enable the subway layer.
3. Locate Berlin’s metro line U6.

Expected behaviour
The metro line should use the color specified in OSM (#8C6DAB) instead of the current blue color.

Actual behaviour
Line U6 is shown in blue.

Screenshots

I really would have liked to fix this issue myself and tried finding the cause by examining the project source code, but the codebase is simply too big for me to understand. Since the color is specified correct in the OSM data, I assume the issue is somewhere during the parsing process.

Isn't it the correct color btw? https://cdn.organicmaps.app/subway/render.html#berlin

[Hallilogod]

Yeah, that one is indeed correct

[biodranik]

I mean, on your screenshot, the color is also correct:

It isn't, on my screenshot its blue but its supposed to be the purple shade you sent

So the problem seems to be in the renderer of the app, It happens both on the mobile and desktop app

The color looks just very slightly off due to mobile rendering:

I wouldnt say its very slightly, to my eyes the line is clearly colored in blue and not just slightly off. Also it happens on the desktop app aswell
