Here's a few pictures to show the effects of different washes/dips on a blue suitable for Napoleonic French. (apologies to any manufactures missed out, this is what I had on my painting desk at the time)
All the figures were completely basecoated in Regal Blue from the Citadel paint range marketed by Games Workshop. It is a medium dark-ish blue bearing in mind that the wash/dip will darken it further. The main aim is to find a one stop shop for anyone doing French in blue in large numbers.
Figure 1, untouched Regal Blue. (click on the photo for a larger version)
Figure 2, Army Painter Strong Tone (acrylic) straight from the dropper bottle.
Figure 3, Army Painter Strong Tone (acrylic) diluted 50/50 with tap water.
Figure 4, Army Painter Dark Tone (acrylic) straight from the dropper bottle.
Figure 5, Coat d'arms Black Ink Wash undiluted.
Figure 6, Coat d'arms Chestnut Ink Wash undiluted.
So there you go, form your own opinions please.
Here are mine:
Figure 1, Regal Blue unwashed. OK as it stands but depends on the figures natural shadows, quickest to finish.
Figure 2, Undiluted Strong Tone, quite OK on the blue but perhaps too severe on lighter colours i.e.pants.
Figure 3, Diluted Strong Tone, similar to number 2 but perhaps gentler on lighter colours.
Figure 4, Undiluted Dark Tone, not a lot different to number 2.
Figures 5, Undiluted Black Ink Wash, way too severe.
Figure 6, Undiluted Chestnut Ink Wash, wrong, wrong, wrong.
