#515151 Hex Color

#515151 provides a strong 7.9:1 contrast ratio against white backgrounds, which comfortably exceeds WCAG requirements for accessible body text. This makes it an ideal, safer alternative to pure black for long-form reading interfaces or UI labels.

Pair #515151 with desaturated blues or soft, muted greens to create a calm, professional aesthetic. Using slate or sage accents alongside this neutral grey helps maintain a sophisticated, low-contrast visual hierarchy that feels modern and intentional.
