About Color.review
Overview
Color.review is a modern web tool for exploring and finding accessible color combinations. It helps designers check the contrast between foreground and background colors against the WCAG 2.1 accessibility standard.
An estimated 217 million people live with a visual impairment, and color perception varies widely. This tool helps creators ensure their work is readable by as many people as possible, including those with color blindness, by checking contrast ratios against WCAG AA and AAA levels.
Key Benefits
- Checks contrast ratios against WCAG 2.1 AA (4.5:1 for text, 3:1 for headlines) and AAA (7:1 for text, 4.5:1 for headlines) standards.
- Supports multiple color formats including HEX, RGB, HSL, CMYK, and HSV for both foreground and background colors.
- Provides a direct shareable link for every color combination checked.
- Includes a random color generator and flip button to swap foreground and background colors.
- Offers a random background color feature to quickly test different combinations.
How It Works
You enter a foreground and background color using HEX, RGB, HSL, or CMYK values. The tool instantly calculates the contrast ratio and displays whether it passes WCAG AA (4.5:1 for text, 3:1 for headlines) or AAA (7:1 for text, 4.5:1 for headlines) standards. You can flip the two colors, generate random backgrounds, or copy a direct link to share the specific color combination.
Use Cases

- Brand designers ensuring their color palette is readable for users with visual impairments or color blindness.
