The New York-based owners of Sears Tower want to know if adding silver will bring in some green.
Sources said the owners are considering an expensive paint job, recladding the tower in silver. Since its opening in 1973, Chicago's iconic tower and the nation's tallest building has been adorned in classic black.
A brighter look could draw fresh attention to the tower, which has struggled to hold tenants against newer generations of office buildings. Silver could figure into a broader effort to "rebrand" the building and highlight its advances in energy efficiency.
