The color choices were poor in my opinon. The green for pro allied neutrals is distracting and loud compared to its grey and white neutral counterparts.
If ever a new edition of this map is made I would much rather the neutrals be similar colors, and beneath the territory name it indicate their leaning, and perhaps some minor rules there too.
Brazil might say
(Pro-Allies after US is at war)
While Mongolia might say
(Pro-Soviet if Japan Attacks USSR)
