This 2 - Bay ACF Center Flow Covered Hopper with Round Hatches is painted light grey with red, white and blue Union Pacific Shield and car lettering is in black.  It was built by American Car & Foundry.  It was part of a large series of cars built for the Missouri Pacific, which merged with the Union Pacific Railroad in 1982.  Union Pacific first used an early shield design for their Company Logo in the late 1980's, and while an enduring symbol of the railroad, it has gone through many changes in its over 100 year history.  The current shield and "Building America" slogan was trademarked in 2001 and the Company began using it extensively in 2002.
