[OSM-dev] Change Stylesheet of Map

The way I do it is to install the map data that I want to render in a
postgresql database using osm2pgsql, then render it using mapnik.
The mapnik stylesheet is usually called osm.xml, and it contains the
definitions of the colours for the various lines (motorway, primary etc.).
It is a complex file though - you will need to change <style> definitions.
The instructions for getting it working to render tiles are in the wiki (
I would first get the default mapnik rendering working, then just start
doing minor changes to the osm.xml file to see how it looks.

An alternative would be to do the rendering using osmarander (
http://wiki.openstreetmap.org/wiki/Osmarender).  This can work directly on
.osm files, avoiding the postgresql setup bits - it has its own style

Good luck!
