I haven't been able to locate a speed key for JOSM's color coding when using "Car" mode for coloring GPX tracks by speed. Where can I find what color corresponds to what speed? |

You find the relevant section of code here. The default color is HSB((v / 45 * 300), 1, 1) where v is the speed in m/s. Hmm, could I get an example of how to calculate that? I definitely appreciate the comprehensive answer, but not sure how to use it.

OK, I stumbled into what the HSB is by accident. For others trying to find how to figure this out, it's at http://www.tomjewett.com/colors/hsb.html

Rationale: I'm looking to update the "maxspeed" rendering style for JOSM to support the full range of US speed limits, and to get color consistency with GPX rendering.
