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). Btw beside of this extension last update is 2017, I saw some people saying this "not working", Idk if this because it's not working on some website or they forgot to refresh page. Because you literally need to REFRESH or RESTART BROWSER anytime after installing an extension. Note: btw on google search, I saw it's working but,, with the low-contrast mode it's make some things of article being highlighted (idk how to describe it) iis that normally like that or..? I don't have problem at all with that I just want to mention that. (here the photo since I am not good at describe thing:https://i.imgur.com/2WSyvmq.jpg)

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.
