ColorAdapt od Zaven Melkumyan

ColorAdapt helps people with color vision deficiencies read and tell apart the colors used on web pages.

Choose the color-vision profile that matches you (protanopia, protanomaly, deuteranopia, deuteranomaly, tritanopia, tritanomaly, achromatopsia or a custom profile). ColorAdapt looks at the colors of the page you are viewing, estimates which text and interface colors are hard to tell apart for that profile, and changes only those, by the smallest amount that helps. Turn it off and the page returns as the site made it.

What it does
• Adapts text and interface colors that are hard to distinguish for your profile, leaving the rest of the page alone.
• Adds small non-color cues (a check, a cross, an outline) where color alone carries a state, when the page's markup makes the state clear.
• Helps tell chart series apart with line styles, markers and patterns in supported SVG charts.
• Adapts single-color icons (inline SVG, and optional small image icons).
• Developer audit: a read-only report of color-dependent problems on a page, with evidence, exportable.
• Optional, off by default: AI-assisted review of audit findings that need a human decision, using a language model that runs on your own computer.

Privacy
• By default ColorAdapt sends no page data to external services. No telemetry, analytics, ads or account.
• Settings are stored in your browser.
• The optional AI-assisted developer review is disabled by default. If you run it, ColorAdapt may send a small sanitized semantic context to a local loopback AI runtime on your computer (for example Ollama). Firefox asks for your permission first (optional "website content" data permission), you can withdraw it at any time, and nothing is sent without it. There is no cloud fallback and no model is bundled.

Please note
• Adaptation is an estimate from common color-vision models. It is not a medical tool and cannot restore color vision.
• Complex graphics and some pages may stay unchanged, and some cases are left for manual review. ColorAdapt does not make a page WCAG-compliant.
• The interface is currently in English.
• ColorAdapt needs access to websites in order to adapt them.
