Sim Daltonism Overview

What is Sim Daltonism? Sim Daltonism is an app that allows users to visualize colors as they are perceived by people with various types of color blindness. It can be used to check the accessibility of websites and user interfaces, improve visual designs for color blind people, or simply to better understand how color blindness affects color perception. The app acts as a filter for what is under it, and users can manipulate windows from other apps located under it. Sim Daltonism can simulate the vision of many forms of color blindness, including red-green, blue-yellow, and all colors. However, the colors shown are only an approximation, and the simulator cannot represent everyone's vision. The app is open source and is also available for iOS.

Sim Daltonism Features and Description

1. With this app you can check the accessibility of websites and other user interfaces, make your visual designs better for color blind people, or just play around to better understand how various color blindness types affect color perception.

2. Sim Daltonism lets you visualize colors as they are perceived with various types of color blindness.

3. Move the Sim Daltonism window over something on the screen and see what it looks like with a color blindness.

4. Nevertheless, Sim Daltonism is a good tool to better understand color blindness.

5. Color blindness varies from person to person and the simulator cannot represent everyone’s vision.

6. From the perspective of a color blind person, some colors are impossible to distinguish.

7. Sim Daltonism is fast enough to filter a video in real time or to have many filter windows active simultanously.

8. The Sim Daltonism window acts as a filter for what is under it.

9. But you can change this so the filter window follows the mouse pointer, displaying the area around it.

10. Many other factors can affect the results, such as the automatic white point calibration of the camera.

11. You can click inside and manipulate windows from other apps that are located under it.



Pros:

  • * Sim Daltonism provides a completely independent and non-intrusive overlay to simulate how users with color vision deficiencies see the interfaces we're building
  • * It works on Mac and Windows
  • * It is a great tool to have while designing
  • * It completely changes my workflow

Software Reviews and Criticism

  • By gbbowers

    Indispensable tool for checking design against CVD

    I use and highly recommend SD to my design colleagues as it provides a completely independent and non-intrusive overlay to similuate how users with color vision deficiencies see the interfaces we're building, and if they'll notice the differences in state change. My only problem with the app is that it doesn't seem to currently handle the dark mode in PC correctly, which causes the icons used for controlling the type of CVD simulated to become essentially invisible (black icons on a black toolbar). It's an ironic oversight, and I kind of have to guess where the icons are, usually hitting the refresh-rate menu instead. Should be a simple fix, so I hope the developer can take a minute to update the app.

    Life-saver

    Still the best way to roll through all the relevant color blindness checks.


  • By Mattinsky F.

    An old standby lives up to its reputation

    I’ve long used SimDaltonism as a stand-alone app to evaluate how websites appear to those affected by many types of color blindness, and I’m glad to see it’s still around. Any time I use color, I like to do a quick run through all the types (by typing Command-1 through Command-9 in sequence) to get an idea of how differentiable the selected colors are to all users. It’s an important tool supporting what should be a content developer’s highest goal: Ensuring content is equally accessible to all.

    Great little app for designers – and am glad that it is free

    A must-have for designing with accessibility in mind and for analyzing someone else’s work. Also great for educating other designers on how people with color blindness actually see their work.
