How many Colquhoun tartans are there?

[Tobus]

And here is the piece of Wilsons' Colquhoun in the Highland Society of London's collection sealed by the chief in 1817.

Wow, thanks for posting that. The colours seem to be about what I thought, but the overall effect is not as interesting as I thought it would be. Some of the other tartans you've done in Wilsons' colours have really caught my attention, mainly because I like the green and red combinations. This original Colquhoun example, though, just has the same overall effect as any other "modern" variant, to my eye. I do find it interesting, though, that the white stripes are much wider on that original example. I wonder how or why it got narrowed down in the official sett that's used today? Any idea?

Bruce Scott, great pic of the chief! I thought I'd add this one as well (from the clan website). He apparently prefers to wear the darker "modern" colours, but Lady Colquhoun likes the "reproduction" tartan like I do. It's a great example of the official usage of different colour variants.
