If you add more gray to a color, it make the color a darker shade of whatever the color is, if you were to add white it'd be a lighter shade of color
The most important limitation of stone is the lack of tensile strength, the capacity of a material to withstand binding.
Stone is durable and impressive stuff, but it's also challenging to quarry, and heavy to move, and it has tension and stress limitations. Where there are resources available to excavate and cut it precisely, stone can be an extremely strong and useful natural material. Unlike brick, it can be stacked without mortar and support heavy vertical loads. Stone resists deforming, weathers the elements well, withstands fire and helps maintain stable interior environments.
