Developer
A free desktop utility that checks and fine-tunes foreground/background color combinations and simulates vision deficiencies to help content meet WCAG contrast requirements.

This tool lets users pick foreground and background colors (via eyedropper or manual entry) and displays contrast ratios according to WCAG 2.0–2.2, with precision and format options for HEX, RGB, HSV and HSL.
Adjustable sliders and color-swapping make it easy to move from failing to conformant contrast levels, while alpha transparency for foregrounds and a sample preview show both text and non-text contrast outcomes.
Built-in color-vision simulators cover multiple deficiency modes, results can be copied in short or long report formats, and preferences include language, theme (light/dark/system), shortcuts and update settings.
The application is distributed with source and support links on GitHub, has prior non-Electron releases archived, and is provided without warranty under open-source licensing terms.
