Slate
Graphite-leaning blue-grays built for editorial dashboards and technical UI shells.
Slate is the designer's answer to carbon fiber: a cool, serious neutral that keeps interfaces razor sharp without turning pitch black. The subtle blue undertone prevents surfaces from feeling lifeless, which is why modern dev tools, writing apps, and collaborative dashboards lean on Slate for their base layers.
Lean into the 700-900 values for immersive hero surfaces, then climb toward Slate 300 for dividers that feel hand-drawn rather than mechanical. The relatively high chroma makes white typography glow, giving you AAA contrast ratios with less eye strain.
