Actually got recommended to this extension from an article, I just feel i wanted to try it although i don't need it.. But to be honest this extension help my eyes from getting hurt than made it dark theme (i don't really like dark theme, also this is just my opinion). |

I'm a color vision expert and I must say this colorblindness simulator has a lot of shortcomings. It shows protanopia red way too dark, as well as deuteranopia red. It also shows protanomaly and deuteranomaly red hues way too reddish than what they truly perceive them. Their reds are much more closer to yellow hues. Tritanomaly simulation is almost the same as normal vision which is totally wrong. Tritanopia simulation is also wrong since it shows that they practicaly see a whole hue circle with some saturation loss, while in reality they only perceive two hues - our reddish pink and cyanish hue. All in all, if you want to use this extension, use only protanopia and deuteranopia simulations since those are the closest to being correct, but keep in mind that reds are represented darker for both types than what they should be, especially for deutans who see red wavelengths much brighter relative to green wavelengths (they still see both colors as yellowish hues) compared to normal vision. Deuteranopia simulation is actually very close to being correct if it was named protanopia, it just needs a slight double grays (around pink and aqua green) position shift. |

I had to restart my computer, but it works. It has a nice range of colour blindness to chose from, and you don't even have to reload the page as it works instantly! I would recommend this to anyone. |

Works well enough, but I have to reset it every time I change the page. I saw that you were going to update it to where it stays, even after a refresh, but until then, I recommend other extensions, such as colorblinding, which can do the same thing, only it does what your app cannot. |

Shame it doesn't work on YouTube videos when you open them in full screen. |

Quite helpful! Just wish it worked on local files. |

I enjoy the simple, clever technique for applying the filters! |

It does the job. One thing I would suggest is to use the common name for the type of color blindness. I wanted to test what it would look like to specifically red-green color blind individuals, so I had to Google red-green color blind to figure our that "Deuteranopia" is what I was looking for. It would ideally be written as "Deuteranopia (red-green)" in the menu. |
