As far as I know, there are only a few manufacturers that make their regular commercial items in the darker coyote brown.
498 brown -
Paraclete
SOE
Kifaru
Camelbak
Khaki -
Eagle
SOTech
Tactical Tailor
HSGI
Blackhawk
Tactical Assault Gear
Emdom USA
SDS
Some manufacturers offer both a khaki and 498 brown color, like Battlelab & CSM Tactical.
And then there are companies like Kifaru and HSGI will make whatever in whatever cordura you can get them. There are always exceptions, too... I have some khaki Paraclete pouches, and Eagle and HSGI makes/has made stuff in darker brown. It can be confusing at best.

So as to not stray too far off course, Azsarge's gear does look pretty cool. I really like the GP Pouch and the Admin Pouch.
It doesn't seem to turn up too well in these photos, but the Battlelab pouches are at least twice as dark as the SDS IRACK underneath. It'll all be dirty colored eventually.
