Actually the hose that I think look best with IOS are Royal Blue, and Claret. I think what makes these hose look good with IOS is the fact that those colours don't appear in the tartan.
The hose I want to get next, to wear with my IOS, are some Claret shooting socks with yellow check tops, neither claret nor yellow appearing in the tartan.
Like this!
In other words I like to have things contrast rather than match.
