Sometime
between the WAS and SYW Prussian dragoons switched their coat colour
from white to blue, the date of this change I'm unsure of.
Furthermore the shade of blue if often shown as any shade between
light blue and medium blue. Kronoskaf has an interesting article
by a major contributor Ibrahim90 suggesting a much darker shade of
blue.

I attach
a picture (where I got it I'm not sure) of an actual Dragoon
coat,either SYW era or even Napoleonic, that shows the colour I am
aiming for, bearing in mind that certain liberties need to be taken
the smaller the figures being painted.
Here is
the whole regiment, five squadrons strong, 35 figures.
