UI Component Sandbox
Live preview of real-world design components rendered using your calibrated colors.
Legibility designed for everyone, everywhere.
Contrast ensures information is accessible to individuals with visual impairments, aging eyes, and screens exposed to high glare or sunlight.
Small caption note (12px): Standard body size requires at least 4.5:1 ratio under WCAG 2.2 AA.
Information Alert
System maintenance scheduled for midnight UTC. All workspaces remain active.
Mathematical Rigor
Exact relative luminance calculation matching WCAG 2.1 & 2.2 algorithms ensures your digital interfaces pass compliance audits with zero subjective guesswork.
Daltonism Empathy
Protanopia, deuteranopia, and tritanopia simulation algorithms verify your color contrasts hold up under all clinical vision deficiency spectrums.
