concrete paint?

Could anyone tell me where I might find online, a good concrete color paint? Or what paints to mix for the appropriate concrete color? for 35 scale.

Thanks all

Pat

Floquil makes a color under their model railroad line called “Old Concrete” that looks just like the real thing.

Badger makes one too

And so does Woodland Scenics, but theres is more like a wash that soaks into the “pores” of plaster parts.[{(-_-)}]

If you want enamel, try Humbrol. But I mixed my own last week. Equal parts of Humbrol light oak (more like an off white) and light grey, it came out perfectly.
