The Swedes, Dutch, Danes and Germans of the Thirty Years War all had uniformed infantry units. Some brigades and regiments also had colour names. Sometimes there two things were related.
Coloured Infantry Brigades
The colour of a brigade had nothing to do with the colour of the uniforms (Brzezinski, 1991).
Coloured Infantry Regiments
The Protestants were also fond of regiments with colour names (Brzezinski, 1991). The names were more about the colour of the flag rather than the coat colour, but some did have matching uniforms. Examples of units, most of which were mercenary, with the date they were raised/named.
German Coloured Infantry Regiments with uniforms
1620-21 Mansfeld formed the Red, Blue, Yellow and Green regiments.
Danish Coloured Infantry Regiments with uniforms
1625-26 the Danes formed the Red, Blue, Yellow and Green regiments. Of these the Red and Blue regiments definitely had uniforms of a matching colour in 1626, light blue in the case of the Blue regiment.
Swedish Coloured Infantry Regiments with uniforms
1625-27 the first Swedish coloured regiments acquired their names, although the units already existed:
- Yellow. Raised 1624 and named “Yellow” from 1626, and had a yellow coat.
- Blue. Raised 1624; renamed “Old Blue” from 1634; had a blue coat.
- Red. Raised 1624-25; had a red coat.
- Green (raised 1627; unclear if had a green coat but some units were clothed in green).
1628 “New Blue Swedish Regiment” (as distinct from the “Old Blue” mercenary unit).
1629-30 the Swedes raised new coloured regiments: Three Black (1629), a fourth Black (1630), Orange (1630), Brown (1630), White (1630)
