Hesse-Kessel gun color of the SYW

So I am paddling through the Net, looking for neat things of wargaming or military history and I come across this well researched blog on ordinance of the Seven Years War.  http://crogges7ywarmies.blogspot.ca/



and the entry about the Hessian artillery is interesting if not aggravating.

Why aggravating?  Well, if to be historically accurate, I will need to not only repaint my cannon (a difficult proposal as they are glued to terrained bases), but I must paint them in white and red!  The colour scheme seems very gaudy to these 21st century eyes.
With much else to paint, do I go back and spend some time on this?  Hmm.

White and red?!
Yes, yes, the ducal colours and all that. But really.  Tough colours to paint at the best of times......
