In 2007 I took part in Skeive kunstnere’s art exhibit, during Oslo gay pride. I exhibited four pictures based on Ishihara color tests, but using gay, lesbian and transgender symbols, instead of letters and numbers. Each picture was printed on 50x50cm canvas. The idea behind the images was that we all see things a little different. What is appealing to one person, may be unnoticeable or repulsive to the next.
The images were made using Inkscape, svg and php. I used Inkscape, an open-source vector drawing program, to draw the different gender symbols. I then wrote a small program in php, that took those images and made Ishihara’s out of them, as svg files. I guess you could call it programmer art. 🙂
If you can’t see the one on the lower left, don’t worry, you’re not colour blind. It’s the one representing heterosexuality, and as a joke, I put nothing in there…after all, I personally can’t “see” heterosexuality. 🙂
On the other hand, if you can’t see the symbols in any of the other three, you might actually be colour blind! Though, please don’t use these as an actual test, and go see a doctor if in doubt, it might just be that your monitor has wonked colour settings.
