I made some uniform concepts to go with some of the helmet concepts red, yellow, white, black, and grey.
May 2, 2014 uniforms Red White
I like the idea of the Chiefs using a red brushed metallic logo and stripe if they ever decided to go with a white helmet. I think the KC logo or the Arrowhead would look great in the red brushed metallic finish.
The headdress helmet will never happen but it could be really cool. I used a real headdress for this one. I think with all of the great HD photos and printing that using a real headdress picture is the only way to go. I think the cartoon looking graphic would be a bad look. 
There are a ton of hats out there that feature the KC white and black logo on a red background so why not try it on the field.
The three below are just some random ideas I ran with for a minute. I am not really a fan of these for the Chiefs but I thought I would share.
This one I was thinking a gold metallic logo like you see on fire trucks might be cool. I personally have never been a fan of the yellow in the uniform so I replaced yellow with gold. I haven’t made any uniforms using gold instead of yellow yet but they are coming.
