User quotes:
For me as a man with normal vision it was a shock and an eye opener to see what it means to be colorblind. Of course I knew about the existence of colorblindness, but I discovered that I had no idea what it really means. I became quite interested and followed many of your links to learn more about this deficit. I use vischeck to ensure that our site is at least readable to people with colorblindness. Thank you for this very interesting view in the world of the colorblind!

  • Daltonize accepts most common image formats. However, we recommend that you use PNG or JPEG format for uploading large images as these tend to transfer faster.
  • For PowerPoint slides, you can save all your slides as PNG images with "Save As..." and run Daltonize on each slide.
  • Uploading a large file may take a while - please be patient!
