User quotes:
I just wanted to let you know I think your site is awesome. As a high school student, I've never really told anyone that I was colourblind - until it was brought up in a biology class. Being the curious folks, high school students are, I was bombarded by 'what colour is this, what colour is this?' and 'what *can* you see?'. Thanks to your site, I can actually show them what it's like to be colourblind, plus explaining some facts to me. Just wanted to show my appreciation,
-Paul F.

VischeckJ - Run Vischeck Anywhere

To run VischeckJ, first install ImageJ, then download VischeckJ.

Note: Installation instructions are also available in Japanese, courtesy of Masataka Okabe.


VischeckJ is a plugin for the ImageJ image processing program from the US National Institutes of Health (NIH). Both ImageJ and VischeckJ are free. Because ImageJ is written in Java, it will run on most common operating systems, including Microsoft Windows, Macintosh OS, and (our favorite) Linux. And because VischeckJ runs under ImageJ, you can now use Vischeck on any of these operating systems as well!

To run VischeckJ you first need to install ImageJ. You can get ImageJ from the NIH site.

Then install the VischeckJ plugin in the ImageJ plugin folder. Do this by copying the VischeckJ files to the 'Plugins' folder in your ImageJ directory. It's a bit like installing a photoshop plugin.

Now you can run ImageJ. The VischeckJ plugin will appear under the 'Plugins' menu.

You can simulate any of the 3 types of color blindness on the selected image by hitting the appropriate button. Here's an example of the ImageJ sample image 'fluorescent cells' as seen by a deuteranope.
