Smithsonian Institute 175th Anniversary Logo

Normally the Smithsonian logo features a yellow sun on a blue circle. Wanting to keep the colors and shape of the original for their anniversary design, their team separated the blue from the yellow, placed the sun on it's own in the gap between the 7 and 5, and then used that backgroudn blue for the color inside the number in this logo. The traditional word mark on the bottom rounded it out and made it easy to recognize.
