Color Eye Tool

The Color Eye Tool analyzes color pair relationships to support digital design decisions. It targets readability, visual harmony, and perceptual accessibility for UI components, dashboards, and marketing visuals. By evaluating two colors across contrast, hue balance, and simulated vision conditions, it helps teams avoid problematic combinations before implementation. This reduces rework, speeds up design validation, and improves consistency across branding and product experiences.
The core engine computes WCAG-aligned contrast using relative luminance, performs hue-difference checks on a perceptual color wheel, and optionally simulates common color-vision deficiencies. Users input two colors in hex or RGB, select a mode (contrast, harmony, accessibility), and set thresholds such as a target contrast ratio or a harmony score. The tool returns a numeric contrast ratio, a harmony score, a pass/fail verdict, and actionable hex adjustments.
What sets Color Eye Tool apart is its mix of automated palette adjustments, multi-mode evaluation, and accessibility-aware guidance that reflects real viewing conditions, including light/dark modes. It supports exporting results, integrates with design systems, and serves designers, developers, and QA teams seeking faster, repeatable color-validation workflows.
