About the comings and goings of hose colour fashion, in Victorian times we only have one large colour sample, The Highlanders Of Scotland, in which we can see over 50 pairs of hose

30 diced
13 tartan
5 taupe
5 mid-grey
1 charcoal grey.

In The Kilt (1914) it is stated that Morning Dress hose should not be tartan.

My catalogues from the 1930s state, concerning the hose worn with Outdoor/Morning/Field/Day Dress:

"self-coloured to match the tweed jacket and vest" (sic)

"plain stockings in a shade to tone with the jacket"

These catalogues don't list the hose colours offered, but a 1950s catalogue offers Lovat blue, Lovat green, and Fawn. I have colour photos from that time showing men at Highland Games wearing these very colours with matching tweed jackets.

Catalogues from the 1970s are offering ecru, navy, bottle green, fawn, Lovat blue, and Lovat green. A catalogue from 2009 offers these exact colours.

With Pipe Bands, they nearly all wore tartan or diced hose up until the 1970s when most went with "natural" Aran hose or ecru/cream ordinary kilt hose.

With the 1990s came the pure white "popcorn top" hose, and more recently black, charcoal, and navy have taken hold.
