"Viking Style" Brouge lacing?

[Tobus]

Bison described as a colour I actually understand as brown, but why not just call it brown?

When a supplier sells kilt hose in multiple shades of brown, they need some way for customers to differentiate them. The most logical way would be to use names that people can associate with what they see in nature, or common items they see in their everyday lives which help them envision that colour. This is commonly done with all colours. For example, nobody complains about the use of the colour "mustard". Why not just call it yellow? Well, because it's an apt descriptor that implies a deeper tone of yellow than other lighter yellow shades. Or the colour "salmon" being used to describe a deeper orange-pink hue. "Charcoal" is a very accurate descriptor of a dark grey that simply can't be captured by calling it dark grey.
