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.
For instance
Brazil might say
Brazil (Neutral)
(Pro-Allies after US is at war)
While Mongolia might say
Mongolia (Neutral)
(Pro-Soviet if Japan Attacks USSR)
