Once the undercoat is dry I continue with the next step and that is to cover the main large areas of colour. In this case my regular Union Regiments get Sky Blue trousers.
This can be applied fairly quickly with a large-ish brush as it goes nowhere near the face or hands and it doesn't matter if it overflows a bit onto the boots or the jacket. They will be overpainted later in a darker colour.
This unit is destined to be Berdans Sharpshooters so they get both trousers and jacket in dark green with no trouser stripe. Again this only has to be tidy around the neckline and around the hands on the rifled musket. It won't matter if the backpack gets covered, it will be overpainted later.
A family crisis has interrupted this painting session so the blue coats will have to wait until next time.
