Is this the official colourcontrast.cc tool?

Yes. Uwarp embeds the public site at https://colourcontrast.cc/. Open it in a new tab if the iframe blocks a control you need.

What is a colour contrast analyser?

It measures the contrast ratio between two colors—usually text on a background—and shows whether the pair likely meets common accessibility thresholds for normal or large text.

How do I check color contrast for accessibility?

Set background and foreground colors in the embed, read the reported ratio and grades, then adjust until both normal and large text rows pass your target level before you add values to code.

Is this the same as Chrome high contrast mode?

No. Chrome’s high contrast setting changes how pages render in the browser. This tool calculates color pair ratios for design and development decisions.

How is this different from Uwarp’s Contrast Checker page?

This route embeds colourcontrast.cc. /contrast-checker embeds ColorDesigner’s contrast tool—use whichever interface your team prefers, but do not assume identical controls.

Does Uwarp modify contrast results?

No. Results come from the embedded provider; Uwarp only supplies the iframe wrapper and supporting copy.

Run the colour contrast analyser from colourcontrast.cc. Test foreground and background pairs, review WCAG-style grades, and validate readable text colors.

What is the colour contrast analyser on colourcontrast.cc?

colourcontrast.cc is a colour contrast analyser for testing foreground and background combinations. It reports contrast ratios and pass or fail style outcomes for normal and large text, with controls to adjust colors and preview readability—including text-focused checks people often describe as colourtext review and shape or logo contrast scenarios. This Uwarp page embeds the official tool at https://colourcontrast.cc/ so you can validate pairs next to other color utilities. For a different WCAG checker, see /contrast-checker; for palette exploration before testing, try /color-contrast.

What you can do in the embed

Capabilities aligned with how teams use colourcontrast.cc for visual contrast and accessibility checks.

Live contrast ratio output: See ratio values update as you change background and foreground colors instead of guessing from swatches alone.
Normal and large text grading: Review outcomes for both text size buckets common in WCAG-style readability reviews.
RGB and HSL fine-tuning: Adjust channels numerically when you need repeatable values for tokens, CSS, or design handoff.
Text and shape preview context: Judge readability on sample copy and contrast shapes before you ship buttons, cards, or logos.

How to check color contrast for accessibility

A practical flow for testing colors and locking accessible pairs.

Set the background first: Start with the surface color you plan for a page section, card, or marketing block.
Adjust foreground text or icon color: Tune the text or mark color until the analyser shows a passing grade for your target level.
Validate both text size rows: Confirm normal and large text results so headings and body copy both stay readable.
Record approved hex values: Copy passing pairs into your design system doc, CSS variables, or component theme file.

Tips for stronger contrast workflows

Reduce late QA surprises when testing colors across UI and brand assets.

Check during palette exploration: Run the analyser while you shortlist colors, not only after layouts are finished.
Test print-bound pairs separately: Screen-approved colors can fail on paper; re-check color contrast for print mockups when relevant.
Re-run after small tweaks: Minor lightness or saturation shifts can fail a pair that previously passed.
Open a top-level tab if controls feel stuck: Some browsers limit iframe interactions; use https://colourcontrast.cc/ directly when needed.

Who this embed helps

Teams that need fast visual contrast feedback before implementation or release review.

UI and product designers: Validate candidate text and background pairs on components and marketing layouts.
Front-end developers: Confirm implementation colors meet readability targets before merge.
Design system maintainers: Publish pre-checked foreground and background tokens with documented ratios.
Brand and marketing designers: Check logo contrast and hero text legibility on campaign assets.
