Vischeck logo  

User quotes:
Now I can answer all those silly questions. I am very badly color blind and so, obviously, the before and after images are identical. However, when someone now starts to bug me about 'what do you see' I can just tell them to pick a URL and give it a try. I am told that the results are dramatically different for certain images that involve the problem colors; I have to take that as assurance of the simulation's accuracy.

Try Vischeck on a Webpage

Sorry- the Vischeck ImageEngine appears to be down at the moment. Please try again later.


  • Vischeck URL is still under development. We know that it will fail on many websites. For example, it won't work with sites that do an immediate redirect, use Macromedia Flash, or use certain javascript operations. Frames may also cause problems, but you can run each frame separately to get around this.
  • Style sheets are crudely supported but beware that many variants will give incorrect results. We are working on a new version to fix many of these issues, but our day-jobs keep getting in the way or a firm release date.
  • Processing some pages takes some time- please be patient!
