This repo contains the Mac version. Looking for the JAVA versions for Windows, Linux?

Color Oracle is a free color blindness simulator for Window, Mac and Linux. It takes the guesswork out of designing for color blindness by showing you in real time what people with common color vision impairments will see.

Color Oracle applies a full screen color filter to art you are designing – independently of the software in use. Eight percent of all males are affected by color vision impairment – make sure that your graphical work is readable by the widest possible audience.

Programming of the first version: Bernie Jenny.
Ideas, testing and icon: Nathaniel Vaughn Kelso.

Feedback

Color Oracle is a work in progress and will improve with time and your input. Please share your Color Oracle testimonial with us and send us an email.

Note

Color Oracle is using the best available algorithm for simulating color vision impairment. However, highly saturated color may not simulate well using the present version of Color Oracle.

Development

Requirements

If you wish to build it yourself, you will need the following components/tools:

a recent Xcode
Git

TeamID

Yes. This is a wall of text, but it’s a pretty simple solution for an annoying problem.

The project is configured to code sign the app. For code signing, you need a valid Apple Developer code signing certificate in your keychain, and you need to specify your Apple Developer Program TeamID in the build settings of an Xcode project. The former should be covered by adding your developer account to Xcode Preferences > Accounts > Apple ID.

To add the TeamID to the project, create a new file DEVELOPMENT_TEAM.xcconfig in the Xcode-config folder of your working copy and add the following build setting to the file:

DEVELOPMENT_TEAM = [Your TeamID]

The DEVELOPMENT_TEAM.xcconfig file should not be added to any git commit. The .gitignore file will prevent it from getting committed to the repository.

See the file Xcode-config/Shared.xcconfig for a more detailed explanation of how to set this up for this or for your own projects.

A big thank-you goes to Jeff Johnson who has come up with this way of handling the DEVELOPMENT_TEAM issue for open-source projects.

Without the above solution, every developer would have to change the DEVELOPMENT_TEAM for themselves and keep the change from getting into version control. Otherwise, every other developer would get conflicts and non-working builds.

You can then open the Xcode project file and build.
