How to repaint the Yandex map route line in a different color?

Changing the color of the lines on the map is not provided, here's what you can do through the map designer (according to the documentation):

On the map you can draw:

• tags - entrances, meeting points, etc.
• lines - streets, routes,
• borders, etc. polygons (including those with an inner contour) - houses, cottage villages, lakes, etc.

This card you can:

• insert on a website, a blog or a mobile application, or share a map with which you can interact — for example, move (select an interactive map type) with friends;
• save and place on your website or blog as a picture, share it with friends (to do this, select the static type of card);
• print or save as a picture (to do this, select the printed card type).

You will be able to save your map objects as a file that you can use:

• to import the necessary points in the program-navigators,
• for use with the Yandex.Maps API,
• to view and save data in other programs (for example, Google Earth).
