Well Portugal will have generic units available to the other European factions, with variations where we have information. The marines are the only unique regimental uniform that is known about for the 17th century i.e. green with yellow cuffs/stockings. Apart form that we know almost all the infantry from 1667 onwards wore blue. So that is what we will have to go on I'm afraid because Portuguese uniforms are so poorly documented in the 17th century. Wel also know the lobster-por helmet was sometimes used (because of Pedro II's harquebusier armour in a museum) and that post-independence, most sashes were green or green-and-white.
