Charcoal Slate

Charcoal Slate begins as a gray color on paper, then shifts with every surface, shadow and neighboring material. Its neutral temperature leaves room for surrounding materials and light to pull the color warmer or cooler. Treat the digital swatch as an opening note, then watch a physical sample from morning light through evening lamps.
