Finally got on to undercoating a whole lot of 6mm TBM resin buildings I got for my mainly Scots war of the 3 kingdoms forces. While all the crofts etc are thatched some of the farm buildings, mill, kirk etc have slate roofs.
Looking at google earth etc seems that the tiles on most older UK slate roofs are grey or almost black rather than red/orange etc found in more humid climes.
So am I safe/correct to depict them as various shades of darker grey or even black?
Start with black grey, highlight l
Slate grey, then pick out individual slates that are paler and/or discoloured.
An example at the approximate size and angle of a battlefield view.
Note the difference between light and shade, the "Close, but marginally darker" comparison to tarmac roads.
Also the varied tones on the Nithsdale Road terrace, which I believe had renovations.
There's variation in slate, and replacements are rarely a perfect match, hence the Lord Speedy's suggestion to pick out individual pieces.
I would add a very small amount of blue into the dark grey, as most slate has a slightly blue tinge - but i emphasize a very small amount
Ok thanks for all the quick replies :-bd
I'll try a bit of variation in some tiles and add a little blue to the mix.
Yes lots of slate roofs in the UK - made from actual sheets of slate stone. Which is a pretty dark grey.
Red / orange roofs are from clay tiles and are also in use in the UK now. But not sure of there use over different time periods - but they are less common than slate.
Slate is not terracotta.
