User quotes:
As an optometrist and a deutan, I always found it rather difficult to explain and describe to patients what a color deficiency was like. Your explanations and demonstrations are outstanding- definitely a link I will add to my brown (or is it green?) web page! Z(I thought my dry cleaner was doing a lousy job of getting rid of spots, but I could never prove it!!)

  • 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!
