What is Well, you found a glitch.

The Contrast Checker tool, formerly hosted on Glitch, was a web-based utility designed to help developers and designers verify color contrast ratios against WCAG 2.1 accessibility standards. It provided real-time feedback on foreground and background color combinations, calculating the contrast ratio to determine if text met AA or AAA compliance levels. Unlike complex design software, this tool offered a lightweight, browser-based interface for rapid prototyping. It served as a critical resource for front-end developers aiming to ensure inclusive UI design. Note: As of the current status, the project is no longer hosted, and the domain reflects a service deprecation notice.

Well, you found a glitch. 's Core features

WCAG 2.1 Compliance Validation

The tool automatically calculates the contrast ratio between two colors using the formula (L1 + 0.05) / (L2 + 0.05). It compares the result against the 4.5:1 threshold for AA and 7:1 for AAA standards. This ensures that text remains legible for users with visual impairments, preventing common accessibility pitfalls in UI development.

Real-time Hex Input Processing

Users can input hex codes directly into the interface, which triggers an immediate re-calculation of the contrast ratio. By eliminating the need for page refreshes, the tool allows designers to iterate through color palettes rapidly, ensuring that brand colors align with accessibility requirements without disrupting the design workflow.

Lightweight Browser-Based Architecture

Built using standard HTML, CSS, and vanilla JavaScript, the tool requires zero heavy dependencies or backend infrastructure. This makes it highly portable and fast, loading in under 500ms on standard connections. The minimal footprint ensures that developers can integrate it into their local environments without performance overhead.

Visual Pass/Fail Indicators

The interface provides clear, color-coded visual feedback (Green for pass, Red for fail) for both large and small text sizes. This immediate visual cue helps developers understand the impact of their color choices instantly, reducing the time spent manually checking documentation or using complex design software to verify accessibility.

Responsive UI Design

The tool utilizes CSS Flexbox and media queries to ensure the interface remains functional across various screen sizes, from mobile devices to desktop monitors. This responsiveness allows developers to test contrast ratios directly on the devices they are targeting, ensuring that accessibility is maintained across all breakpoints.

Use cases of Well, you found a glitch.

UI/UX Design Auditing

UX designers use this tool to audit existing design systems. By inputting primary and secondary brand colors, they can identify non-compliant combinations and adjust saturation or lightness values to meet WCAG standards before the design reaches the development phase.

Front-End Accessibility Testing

Front-end developers use the tool during the coding phase to verify that CSS color variables meet accessibility requirements. This prevents accessibility regressions during the build process and ensures that the final product is inclusive for all users.

Educational Accessibility Training

Accessibility advocates use the tool to demonstrate the importance of contrast ratios to junior developers. By showing how minor adjustments to color values can change a 'fail' to a 'pass', they provide a concrete, hands-on learning experience.

Who benefits from Well, you found a glitch.

Front-End Developers

Need to ensure their CSS color implementations meet legal and ethical accessibility standards to avoid compliance lawsuits and improve user experience for visually impaired users.

UI/UX Designers

Require a quick way to validate their color palettes during the design process to ensure that their creative choices are functional and accessible for a wide range of users.

Accessibility Consultants

Use the tool to quickly audit client websites and provide actionable feedback on color contrast issues that need to be addressed to achieve WCAG compliance.
