Interesting to see how the Swedish blue turns out--my French varied enough in color just within the new Croix de Guerre that I wonder if there will be overlap with the Swedes and the French and/or German counters.
Did the Swedes ever overlap with the French in Norway?
Maybe a better solution would have been to make the Swedish volunteers Axis Minor green--no fear of them fighting Axis Minors, and there is plenty of precedent for using that color for nationalities that were only German-allied some of the time. Alternatively, you could give them Japanese yellow or American green.
But anything is better than two-tone, so I shouldn't gripe!
