A colorblind filter for every video you watch
Filmina adds three free colorblind corrections to your browser: Deuteranopia, Protanopia and Tritanopia. Each one shifts the colors in the video so the ones you mix up stand further apart, on Netflix, YouTube and any other site that plays video.
Free on every plan. No account, nothing uploaded. Chrome, Edge and Brave; Firefox in beta.
Try it on a red apple in a green meadow
Reds, oranges and greens are what red-green color blindness mixes up, and this meadow has all three. Pick a correction and judge it with your own eyes. If your color vision is typical, set Viewing as to a type of color blindness, then switch the correction on and off to see what it changes.

Which correction is yours?
Each one is named after the kind of color blindness it is made for, and each works for the milder form too.
Green-weak or green-blind
Deuteranopia
Deuteranomaly, the most common kind, and deuteranopia. Greens, yellows, oranges and reds drift toward the same shades.
-
Red-weak or red-blind
Protanopia
Protanomaly and protanopia. Reds look darker, and closer to greens and browns.
-
Blue-yellow
Tritanopia
Tritanomaly and tritanopia, which are rare. Blues and greens, and yellows and pinks, are hard to tell apart.
Red-green? Try both. Deuteranopia and Protanopia turn colors in different directions and by different amounts, so even if you know your type, keep whichever separates reds and greens better for you. If your color vision is only a little off, turn its Amount down until it feels right.
What it does, and what it can't
What a correction does
It turns the hues of the whole picture and adds some saturation, so colors that fall on the same shade for you land on different ones. We tuned each correction with a standard simulation of color blindness (Machado, Oliveira and Fernandes, 2009), the one under Viewing as above: on average, pairs of colors a simulated viewer mixes up end up further apart.
What it can't do
It can't give back colors your eyes don't see, and it doesn't know which colors matter in a scene. It moves every color in the video, so to someone with typical color vision beside you the picture looks shifted. And it changes only video; the page and images around it stay as they are.
Where it works
YouTube, Netflix, Disney+, Prime Video, HBO Max, Twitch, Vimeo and most other sites that play video in the page. Services that protect the picture still let a browser change its colors, so the corrections work there too.

Questions
About the colorblind filter
- Yes. Filmina's Deuteranopia, Protanopia and Tritanopia corrections work on Netflix, and on Disney+, Prime Video, HBO Max, YouTube and most other sites that play video. They are free, and nothing you watch leaves your device.
- Start with the one named after your type: Deuteranopia for green-weak or green-blind vision, Protanopia for red-weak or red-blind vision, Tritanopia for blue-yellow. For red-green color blindness, try both Deuteranopia and Protanopia: they turn colors in different directions and by different amounts, so keep whichever separates reds and greens better for you.
- Yes. The Amount slider at the top of Looks scales the applied look from 0 to 100%, which suits milder color weakness such as deuteranomaly or protanomaly.
- Yes. Every comfort look, the three corrections among them, is free on every plan, with no weekly limit and no account.
- No. Filmina changes only the video playing in your browser. The page, images and other apps stay as they are; for a filter on the whole screen, use the color filters in your operating system's accessibility settings.
- No. The correction is drawn by your browser, on your device. Filmina never uploads, records or copies video, and there is no account and no analytics.
