About the Slate Cold Gray palette
Cool-undertone slate scale providing crisp contrast for modern developer tools and dashboard interfaces. The scale is anchored at hue 240 in OKLCH, so every step keeps the same hue while lightness moves in perceptually even steps from 50 to 950. The 500 step (#657179) is your base color. Shades 500-950 pass WCAG 2.1 AA against white and shades 50, 100, 200, 300, 400 pass against black, so use the light end for backgrounds and the dark end for text on light surfaces (or vice versa). Each value is copy-ready as oklch(), HEX, RGB or HSL.
