Mizzou? SLU? Lindenwood? Which college or university lays claim to having the most fans in St. Louis? 

Today is College Colors Day, an annual celebration, according to its website, dedicated to promoting the traditions and spirit that make the college experience great by encouraging people across America to wear apparel of their favorite college or university throughout the day.

Here at Patch, we're using the day to find out which higher education establishment has the most support in the St. Louis-community.

I, myself, am a proud graduate of Southern Illinois University in Carbondale—go Salukis!—but am also a huge fan of Mizzou.

What about you? Upload a photo of you, your family, your dog—whatever—displaying your college colors.  

When you're done, feel free to talk some trash at your college rivals (keep it clean, of course).
