why is the mo in baltimore a different color

The "MO" in "Baltimore" painted a different color in the Baltimore Ravens' end zone is a tribute to Mo Gaba, a young Baltimore Ravens and Orioles superfan who tragically passed away from cancer in 2020 at the age of 14. The "MO" is painted gold (or sometimes purple, depending on the event) to honor his memory and legacy. Mo was known for his inspiring positive attitude despite battling cancer from a very young age, and he was beloved by Baltimore sports teams and fans. This tribute symbolizes his lasting impact on the Baltimore sports community and keeps his spirit alive at M&T Bank Stadium.
