I reckon I will do 2 slightly different liveries of 6 figures in each 12 figure archer unit. This group will likely be blue / yellow and white / blue (the first colour is on the right side). I want to use a combination of reds on the other 12 archers, but I've not yet decided the livery. I don't think I want to use the blue / maury combination of Edward IV and co.
I still have a couple of little books of WoR liveries and flags that I got many years ago - I think from the Lance and Longbow society. They are good to look through, but so many nice combinations make deciding on liveries for 6 or 12 figures a bit tricky.
I gave the men-at-arms a thin black wash to highlight the detail on the armour. Trendy 'tinternet paint-heads probably call this pre-shading or something similar.
