While I swear by glove liners too, for this same reason, Cruiser (well, not telescopes anymore, but various other outdoor stuff where I need to occasionallty remove gloves/mittens but still want some coveragge), depending on controsl you're using, might be able to use a pair of shooting mittens to lessen your exposure even more. They split off not jsut the thumb, but the forefinger into seperate fingers, and then other three in regular mitten style. This gives you more dexterity, but still keeps warm (shootesr use them, with guns with big enough trigger guards, to shoot without removing but still have the extra warmth of mittens). Can find them very cheap at surplus stores, might be worth trying to see if they'd work for you.
Anwyay, back on topic.
With a short coat I might coordinate with shoes, but with longer topcoat I'm more likely to choose gloves based on the color of the coat than the shoes. Esp as good chance I'm just wearing plain black rubber overshoes over some nice dress shoes, so by that rule, would always be wearing black rubber gloves to match the overshoes.
