Earth's crust in a nutshell, or rather a soft, stony beige.
Feldspar is a soft brown, close to beige.
It can be described as soft, light, fresh and rather unsaturated.
Set in black, because black reads best on it.
Feldspar is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust and 41% of the Earth's continental crust by weight.
