Do not convert transport route (e.g. metro/subway) colors to palette colors

[Alan-Liang]

Currently, colors of transport routes are being converted into 16 palette colors. This is really bad because people rely on the exact colors to recognize lines, which could deviate pretty far away from the palette colors.

Moreover, there are many transport systems with more than 16 lines, so different lines with (originally) different colors would be represented by the same color. For example, Beijing Subway lines 2, 4, 10, 17 and Daxing Airport Express are represented by different shades of blue ($\color{#00529B}\textsf{2 = 00529B}$, $\color{#008994}\textsf{4 = 008994}$, $\color{#178ABB}\textsf{10 = 178ABB}$, $\color{#00A9A9}\textsf{17 = 00A9A9}$, $\color{#3F48CC}\textsf{DAE = 3F48CC}$), but are all converted into “blue”, making them indistinguishable.

I suggest remove the conversion and use the original colors instead.

Thanks for the report — this is a feature request.

Do I understand correctly that you are asking us to stop reducing transport route colors to a limited internal palette and instead display the original route colors exactly as defined in OpenStreetMap (e.g., colour=* tags), so users can more easily distinguish between similarly-colored transit lines?

Yes.

Thanks for your reply!
