The color(s) black, grey, green, and white is/are claimed as a feature of the mark.
The mark consists of black lettering of "Firearm Shop" under a U.S. Army "tab" which contains the white lettering "Brothers" which has a greyish blue background with a green border. there is also a subdued version just like military patches that would also be a version of this logo also. there are also different versions of the logo that may not say "Firearm Shop" below the tab. So it would be just the Army tab with brothers inside.
