Dusty, sun-baked rock, like the flat top of a desert mesa.
Mesa is a muted beige, close to brown.
It can be described as muted, dull, matte and soft.
Set in black, because black reads best on it.
A mesa is an isolated, flat-topped elevation, ridge, or hill, bounded from all sides by steep escarpments and standing distinctly above a surrounding plain. Mesas consist of flat-lying soft sedimentary rocks, such as shales, capped by a resistant layer of harder rock, like sandstone or limestone, forming a caprock that protects the flat summit. The caprock may also include dissected lava flows or eroded duricrust.
