Hi, i just had it in the game when i crafted a Rubicon Gambeson. I crafted it with Black Wool, and did get a grey Gambeson item when i wear it.

If i go now into "Hide" mode with hide skill, my gambeson changes color from grey to black. It seems like the Rubicon Gambeson item isnt the only one. Several items seems to be bugged not to show the correct production color if you use the collored cloth type.

But if you go in hide mode, it always show the right color (did even worked with pink color on a item in hide mode ^^)

So it seems for me a bug. Not a feature =)
