User quotes:
This is a brilliant website. Thank you! With its help, I am able to demonstrate to my students why colour is so important in user interface design. HCI ceases to be a boring subject and comes alive for them as they realise the impact their choice of colours may have. Thanks again!

Try Daltonize on Your Image Files

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


  • 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!
