|Seriously. Not this colour, or shaded|
variants of it. Really. Even if it's the one
GW put in their terrain pack along with
that brown that isn't soil-coloured...
Rock is not grey.
Specifically rock and stone, with a very very small set of exceptions. are not THIS grey that people always paint them.
This is our old friend RGB #708090 which a decent number of people consider 'pure grey'. The only rocks that come close to that colour are mostly slate and some granite, but in general? Most rocks are no more that shade of grey than most soil is a kid's crayon brown.
We also come back here to how light affects things - if you do a search for Raglan Castle, say, and look at the range of images on offer, see how much the colour varies depending on time of day, sun vs cloudy sky, etc. The guidebook actually describes it as 'yellow sandstone'!
So what colour is stone?
Those lovely folks from Munsell, not content with keeping archaeologists and soil scientists happy, do a series of rock colour charts too :D That aside, if you think a 200 buck colour chart is a bit much for your hobby, I suggest a bit of Googling, and trying to match. Be aware, though (and this is something we need to discuss in a later article), large expenses of colour in smaller scales look wrong unless you lighten them and de-saturate them a bit from their original shade.
I'm currently using my three stage drybrush over Sandtex Bitter Chocolate that I use for soil, and then knocking back the very pale final shade of cream/'magnolia' with a wash of Army Painter Soft Tone ink, which also has the advantage of restoring some of the surface detail if I've been a bit heavy-handed. But it's up to you - that's one specific rock colour/shade out of a wide spectrum from reddish to almost grey, and many points in between and outliers.

Ok. So. Anyone any suggestions for a water-based equivalent to Army Painter Soft Tone that I can buy in larger quantities than 15ml droppers? I may have a LOT of stone to paint.
