I showed my boss the new FileMaker app I had created for the lab, and he said: "Could you add this info?" which was right there in front of him - that's when I realized he is red/green blind and simply couldn't see the writing. I found Sim Daltonism and since then haven't created an app, a web page, or a presentation without first checking it with Sim Daltonism. Essential app in my opinion.

Brilliant. Very useful for web designers who are into standards compliancy and accessibility (ie. who are into designing properly). Well done.

I'm color blind and I like this app to show the world I see.
Thanks a lot

Cute.

A problem, though. When the display window "Funhouses" (Move the view to the window itself... much like in the sample picture), it starts to chug majorly.

I made the mistake of hitting the button to maximize the window size in an (admittedly foolish) attempt to basically get a more firsthand feeling, where my entire screen would be under the effect.

While my whole screen was indeed colorblind, the problem is that Sim Daltonism is showing Sim Daltonism showing Sim Daltonism showing Sim Daltonism. The screen immediately filled up with menubars and the display window lagged to high hell.

Fortunately, the window functions were still passably responsive and I set the window back to its original size without having to force quit the program or otherwise having it crash.

I think it definitely needs some optimization so it doesn't lag so easily, and it should preferably not show its own window in the display

On the more positive side though:
- It didn't crash during aforementioned full-screen funhousing
- It's an interesting concept
- The fact that I can make more than one window and set the filters independently is great.
