Same thoughts here. There are plenty of good quality tools that can both provide a simulation of colour vision deficiency and filters to help those who have it. And it seems like almost all of such tools provide vastly different results to what we see here. I myself have a tritan-type CVD and for me the "simulate colourblindness" thing makes all the colours extremely washed out, making everything B&W with some slight accents of blue. Everything looks very odd and vastly different from how I see normally when I have this feature on. I'd assume I wouldn't see too much of a difference if this thing worked as intended, but it makes things look as wrong as they can possibly be. (Like, it makes blue things red and red things... grey? somehow???) On the other hand, the filter for colourblind people just makes things less vibrant, making reds look washed-out. I also have friends with deutan and protan CVD and, it seems like they have more-less the same opinion on these filters and simulations. It is quite sad IMO and makes it harder for map devs to optimise their worlds and also spreads misunderstanding about CVD. For example, sometimes people try to play with this "simulate colourblindness" thing on, trying to understand me better, but it just makes things 10 times worse instead. A whole year has passed and nothing really changed about these features. I've used to play with mods that provided good quality filters for people with CVD so I could play different games on VRC that rely on colours with my friends, but ever since the EAC update I can't really do this anymore. I was happy to find this feature when it first came out but I couldn't be more wrong, really. In the state that it's currently in, it's the most disappointing feature for me to this very day. I hope they'll come back to it soon... it would make playing the game so much easier for so many people

I noticed this last night. It's making reds and yellows appear as blue, but to someone with protanopia the color red would appear similar to a dark shade of yellow. Blues appear as yellow but they should be blue because a person with protanopia can still see the color blue. It's almost like the effect is swapped?

Is there a moderator that I could ask to move this post over to open beta feedback?

Agreed, colors shouldn't be washed out as they are now. I've been working on some simulation projects myself, and the daltonlens.org post might as well be considered a bible for accurate simulations. They have a good "So which one should we use?" section that lists out what should be done to be accurate.

In the post, they also reference an open-source Unlicensed (meaning put in the public domain) project that would be great to look at and base the code/shader for the simulation: https://github.com/DaltonLens/libDaltonLens/blob/master/libDaltonLens.c

Overall great to see VRChat finally putting this into the game, however much improvement is needed before it can be considered reliable!

Yeah, the one VRchat is using doesn't just look like it simulates not being about to tell the difference between colors but takes away the saturation too.

Also not color-blind but colorblind people I've known still seem to experience colors' vibrancy within their visible colors
