MEANINGful Monday: Grisaille

Grisaille:

Wall or art paintings executed entirely in a monochrome or near-monochrome palette, usually in shades of grey. A grisaille may also be created as an underpainting for an oil painting (in preparation for layers of color over it), or as a model for an engraver to work from. {A bedroom with grisaille wall by White House designer Michael Smith, a grisaille painting by James Gleeson}
