Pattens Colour Mix-up

[Umo]

I think the color is actually the cloth that adorns the wood.

That's it. It's pretty odd, though. For me, the colour displayed on the item's name should be predominant on both icon and equipped item.
On a side note, this happens aswell for other pattens like [item=8080320]Oak Pattens[/item] (i.e. [item=8080323]Oak Pattens (Black)[/item] are light brown, almost golden).
