On October 30, 2009, Valley Metro introduced a concept paint scheme on two New Flyer C40LFR's which are serving as demonstration units for the new scheme. The scheme consists of a silver body with a green and purple swoosh going from forward of the front wheel to the rear of the CNG tanks. Riders were provided surveys which were collected and information reviewed. This scheme became official on all RPTA-owned buses (not including the LINK buses) built since 2010. The LINK buses used a variant of this scheme, with a purple front instead of silver.
