The material asigned to the mesh is red. That's all.

You must simply change the color of the object. Select it, and with the object selected, change the default color asigned to it, from red to the desired color. You can see the object color in the small color square button next to the object name (right panel)

If by any chance you have a map asigned to the object, you can remove it. Go to the Utility panel (last top-right on the right tools panel), click the more button and select the "Remove UVW/Material" script.

With the object selected, remove the material. You can set its color to grey if you like.

Another chance is (as I can see from your picture you have your object already selected), that you have all the edges selected. Go to the Modify panel, and ensure your Edit Poly modifier (witch I suposse you have on top of the object stack) is selected on the top of the modifier and not in any of the sub-objetcs level (i.e: edges).
