Your question fails to establish certain important parameters. The first would be the type of color process the second would be the characteristics of the black and white image. By that I mean RC or Fiber. Silver Gelatin, Pt/Pd, or inkjet. All of the foregoing would be considered black and white images.

If we were to assume that you meant silver gelatin printed on fiber paper compared to conventional color images then the silver gelatin print would last longer.
