GW Foundation paints?

Hi, what's the use of the foundation paints? I was offered a cheap foundation paintings set, and I dunno if it would be a good purchase, because I don't really understand what are they used for.

Foundation paints have a higher number of pigments and thus cover a surface much better than ordinary colour. For example, you can use the foundation yellow to get a nice yellow coat on a miniature which was undercoated black, whereas you'd need to paint about 3 to 5 layers of ordinary yellow until the black stops showing heavily.

Basically, they take less coats over any undercoat to produce a good coverage.

One use is to provide a good base to put another colour over the top. Mechrite Red looks slightly pink, but a coat of normal red on top of that will give you a solid smooth red starting from a black undercoat. Same with Iyanden Darksun for Yellows.

Other colours like Khemri Brown and Dheneb Stone can be used in their own right as fantastic colours for cloth and such if you want a great beige tone.

Orchide Shade is great for painting orc skin.

Charadon Granite is amazing for any drab militaryish grey/green. Or for basecoating stone. Or also orc skin.

Treat them like you would any other paint really. Add water as with all paints. Even then, they will cover the undercoat in 1 or 2 coats.

So... they would be used only on those situations?

I mean, for any other case, I should use normal ones?

They are not primers, right?

I used this to my first mini as a first layer of paint.

And it workt great

The Foundation paints are brilliant! Combined with the new Washes (and their normal paints for some things) they really can transform they results you can achieve.

I love 'em!

I love the foundation paints. I'm not the best painter, and painting isn't something I jump to but these paints make the job easier. Before these I painted an Empire army with lots of white and blue and it took a lot of coats to get the white correct, it was much easier using foundation paints when I started my brets with my Knights Templar theme.
