All figures were placed on painting sticks and black primed, then "damp brushed" with white and coloured "identifiers" painted on the sticks.
Since then all figures have had at least 5 colours applied (many have more) -- at a minimum every figure has flesh, hair, headgear, coat and breeches painted.
Since I wanted an "irregular Regular" appearance, I have used three somewhat similar coat colours in each unit (painting one stick each of pike & shot with each colour). I then used four varied colours for breeches (painting one figure on each stick with each colour). Also I've varied the hat colours as well.
The result is that no two figures are painted the same way . . . but that each unit will look like a unit (albeit perhaps a bit ragged or with differently aged uniforms).
So, what is left to do? Most of the leatherwork (belts, boots and pouches), most muskets and most metal bits plus a few odds and ends.
Oh yes, I also have four units of Commanded Shot at about the same point in the painting process . . . but all of the mounted still await my brush . . . *sigh*.
