Halo

As far as color, I think the helmets have a light gold hue.
The old helmets with Addidas unforms had a more old gold color.
The difference is not apparent until you look at old game footage next to new game footage.

The numbers on the Addidas uniforms were brown mustard.
The pants on the Addidas were, as I saw them, the exact same color as the current Nike pants.

The Addidas uniforms mismatched gold (helmet, numbers and pants).
The Nike uniforms use the same gold on helmet, numbers and pants.
The Addidas uniform pants never matched the gold on the helmet etc.

What I do agree with is I wish that gold throughout the Nike uniforms was slightly darker, more old gold.
