Has anyone made a colour bliindness simulator?

It seems like something that would be possible to do for photographs, if perhaps not in real time for film without a very expensive graphics card.

Lots of people.

Here's the first one I found.

Do any decent VR goggles have stereo cameras? If so, maybe a real-time 3D version of this could be made.

AFAIK, most augmented reality hardware puts a HUD on transparent glasses. Those wouldn't block the real vision of the user, so wouldn't work for this.

Actually, I suppose the cameras could be a clip-on peripheral?

A quick look for "color blind simulator" shows that phone apps, photo filters, and browser modes all exist towards that end. Having a phone app and looking through that might be a little odd, but less so than walking around outside with VR glasses strapped to your face. (The googling did also turn up glasses that simulate certain kinds of color blindness, but I can't vouch for how good they are or how many kinds of color blindness could be simulated with lenses.)

If you just want to simulate generic color-blindness and you're using windows, it might be easiest to go into settings/accessibility/color filters, activate grayscale, and open up any 3d video game. There are other filters that mitigate the effects of certain kinds of color blindness, and they might be used to get the experience of having a shifted visual color palate. Filters to simulate color blindness as a general setting on your computer are less likely because there's less call to program them, but in principle it's just as easy.

A lot of modern video games HAVE "colorblind mode" in their accessibility options, which will shift all the colors around to make stuff in-game more visible to those with specific colorblindness types. It won't be a "true" experience but it's the closest you're likely to get.

Partial colorblindness might be a bit trickier to find but there's a lot of stuff out there that can simulate total color blindness. In addition to anything with a color setring that can be turned down/off, some camera programs have an effects setting that can be set to black and white

[Rydiro]

Such a filter is one of the easiest tasks for a cpu or graphics card. You just need to take each pixel, look at its color and compute the output color for the type of color blindness of your choice. Should be a few additions and a fixed scaling.

As said, your phone can probably do it in real time.

Depending on the phone.

You don't need electronics for this. Lenses made to filter specific wavelengths of light will do. Even looking at things through a piece of colored glass will approximate the effect. But yes, it would be a piece of cake for modern imaging software.

It has been done for photographs. Search on Google images for "what things look like to people with various forms of colorblindness" and there is a bounty of examples. It is simple crosswalk of the color-encoding of visual files for anything digital, so it shouldn't be overly taxing on computation.
