Colts used to have grey in their uniform?

Here's what I was thinking. A little jazz without any bells and whistles, plus a departure from the Baltimore glory days. The outlines are a little difficult to see, but they are there, around the horseshoe and the numbers/letters.

I like this. It retains the simplicity of the Colts current uniforms, the grey face-mask makes sense, and it ties into the Colts' history in Baltimore, while at the same time establishing a new look for Indianapolis.
