WCAG 2.1 Accessibility & Contrast Ratios

White Text (#FFF)4.47:1 (Fail)
Black Text (#000)4.7:1 (AA Pass)

Algorithmic Formulas & Methodology

Relative Luminance L = 0.2126*R_lin + 0.7152*G_lin + 0.0722*B_lin
Contrast Ratio = (L1 + 0.05) / (L2 + 0.05)

How to use this tool

Color Spaces and Digital Accessibility Standards

Digital color systems serve distinct domains: RGB/HEX for digital emissive displays, HSL for intuitive design manipulation (Hue, Saturation, Lightness), and CMYK for print subtractive inks.

Frequently Asked Questions
