The Persistence of Paint

I couldn't figure out what the original color of this old work truck's paint was. Green? Pink? Gray? What caused the yellow streaks? Was it painted this way, or did these colors evolve with exposure to the elements? Combined with the textures of the rust, glass, chrome, steel and wood, it was a feast for the eyes.
