Hue Shift - Colorblind Filter

Recolors pages, images and video to tell apart colors color blindness confuses. Red-weak, green-weak, blue-weak. No data collected.

Pick the type of color vision deficiency you have, turn it on, and pages are recolored so the colors that used to look the same become tellable apart. Charts where two lines blend into one, dashboards, online shopping, the videos and animation you watch — anywhere a page says something with color alone. This is the opposite of a colorblind simulator: a simulator shows designers what color blindness looks like — Hue Shift is for the colorblind viewer, recoloring the page so you can tell its colors apart. WHAT IT DOES • Recolors the page's own colors — text, backgrounds, borders — and filters images and video, in one consistent scheme • Three types: red-weak (protan), green-weak (deutan), blue-weak (tritan). Pick yours once; it is remembered • Five strength levels, so a partial deficiency is not over-corrected • Goes further than a plain color filter (daltonization): colors that would still collide after filtering are pushed apart in lightness, the one axis every kind of color vision keeps • A new color appearing on the page — a live chart, a loading feed — is folded into the same scheme without reshuffling the colors already on screen • A live preview beside the strength control: a paired swatch shows the correction working, at the strength you picked • Turn it off and every page is restored exactly as it was WHERE IT WORKS • Out of the box it recolors the tab you turn it on from • Press "Apply on all sites" once and it follows you everywhere: every open tab, every new page, until you turn it off • An "ON" badge on the toolbar icon shows it is on • A keyboard shortcut to turn everything off can be assigned at chrome://extensions/shortcuts — paste that into the address bar; nothing is bound by default, so it cannot clash with anything you already use WHAT IT CANNOT DO Honesty about the edges, so nothing here surprises you: • Chrome's own pages, the Chrome Web Store and other extensions' pages cannot be recolored — Chrome does not allow any extension to touch them. The popup says so when you are on one • Some protected video (DRM) is composited outside the page, where filters cannot reach it • A video popped out into picture-in-picture is drawn by the browser, not the page, and keeps its original colors • It changes how colors are displayed to you. It does not change your eyes, and it is not a treatment, a test, or a substitute for one PERMISSIONS • "Read and change data on websites" is requested only when you press "Apply on all sites" — recoloring means rewriting the page's colors, which is what that permission is for. Until then it works on the current tab only, granted by your click • Storage keeps three things: whether it is on, the type and strength you chose, and the popup language if you picked one PRIVACY • No analytics, no account, no tracking • No remote code — everything that runs ships inside the extension and is reviewed by the Chrome Web Store • Nothing is transmitted anywhere. Your settings stay in your browser • Page colors are examined in your browser only, to compute the recoloring Hue Shift is built by Small Labs. Questions and bug reports: support@small-labs.com
