Since I do not like their double AR mag pouch option, I  Want to know if other companys Coyote color is a match to TT.

If it's truly Coyote Brown, then yes.  Specter Gear makes Coyote Brown gear. Eagle makes Coyote Brown gear but most of what they put out is Khaki.  High Speed Gear's stuff is Khaki.  SOTech's gear is called Coyote, but is more a Khaki/dark tan than true Coyote Brown.

Coyote Brown is a chocolate-brown color that's int eh USMC MARPAT design, the dark brown int he 3-color DCUs and is reminiscent of the Nutria Brown used in the SADF Pattern 83 vests and chest rigs.

Tactical Tailor only recently moved to Coyote Brown, switching over from tan, which was about/nearly the same shade as Eagle/HSGI/SOTech's khaki/tan colors

Blue Force Gear, Specter Gear, ATS Gear, and Emdom is darker than TT's.

Tactical Tailor's coyote color is lighter than most other's coyote.

TT Coyote Brown matches the coyote brown on Mystery Ranch Packs

Here's a picture I took.  As you can see, most of the actual Coyote Brown matches, with the Specter Gear CB being slightly off.  It's a little lighter "shinier" than the other stuff, especially under a flash.  In "normal light" it looks brown, but not the same brown as the CB in the other items.

SO Tech's color, which they call Coyote, is more Khaki, and closely matches Tactical Tailor's (now discontinued) tan color, HSGI and Eagle's Khaki.

Hope this helps.

What color webbing is on their multicam gear?  Is it Tan or Coyote?

If you look at a picture of their TTRAC on the website, it shows the webbing on a MultiCam vest:

According to my rep at TT, they haven't changed anything.
