On the internet the is bit of debate about the best colour mixes for Japanese uniforms. I used the Valejo range for these guys. The officer's uniform was a mix of Russian Uniform and Panzer Yellow, while the mortar men were painted with a mix of Panzer Yellow and German Ochre. On reflection the mix appeared bit dark so I will try a variation on the mix for the next batch of figures.
All three figures were then washed with Games Workshop Camoshade which work well on giving the figures a touch of depth.
One the key issues for these figures was to get the flesh tone right. At this scale I added a touch of Panzer Yellow to Sunny Skintone this mix was then washed with Games Workshop's Flesh tone.
I am pleased with the results so far considering I only have around an hour an evening to dedicate to these figure.
