Slate Mauve

Slate

Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism. It is the finest-grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression.

Mauve

Mauve is a pale purple color named after the mallow flower. The first use of the word mauve as a color was in 1796–1798 according to the Oxford English Dictionary, but its use seems to have been rare before 1859. Another name for the color is mallow, with the first recorded use of mallow as a color name in English in 1611.

Slate gray

Slate gray is a moderate shade of gray with a slight azure tinge, which represents the average color of slate, a metamorphic rock often used in stonemasonry. As a tertiary color, slate is an equal mix of purple and green pigments.
