Fix Color Blindness Simulator

Color Blindness Simulator � Engineering for Inclusive Design

Accessibility is not a post-launch checklist; it is a fundamental architectural requirement. The DevUtility Hub Color Blindness Simulator is a diagnostic tool designed for UX designers and frontend engineers to verify that their color systems remain distinct and legible for the ~8% of the male population and 0.5% of the female population with color vision deficiency (CVD).

How it works

Our simulator applies mathematically accurate transformations to your colors based on physiological vision models:

•Red-Green Deficiencies (Protanopia & Deuteranopia): Audit how your primary brand colors merge or disappear for users with reduced sensitivity to long and medium wavelengths.

•Blue-Yellow Deficiency (Tritanopia): Simulate rarer vision profiles to ensure your status indicators (success vs. warning) remain distinguishable via secondary cues.

•Total Color Blindness (Achromatopsia): High-fidelity grayscale simulation to verify that your UI relies on contrast and value rather than color alone.

•Real-Time Palette Auditing: Add multiple HEX codes simultaneously to see how your entire design system shifts under different vision constraints.

The process

1. Palette Ingestion: Enter the primary, secondary, and accent colors from your design system. 2. Deficiency Sweep: Toggle through the six major CVD types to identify "collision points" where two distinct colors become indistinguishable. 3. Corrective Design: Adjust your hues in real-time until your palette passes the distinction test across all vision profiles.

Why it's the professional Fix Choice

Designing for accessibility often involves sensitive brand assets and unreleased UI patterns. DevUtility Hub is 100% Client-Side. Your color palettes are processed entirely in your browser window. We never track your brand colors or store your design tokens, providing a secure sandbox for building inclusive digital products.
