User quotes:
Thank you for the Vischeck upload site. I work as a graphic designer and illustrator preparing information panels. Many years ago I realised that I should choose my colours carefully, as so many people exhibit some degree of colour blindness. I talked it over at that time with a friend who had problems with red/green, and we concluded that I should assume these colours are just shades of grey. Since then I've checked my work by printing stuff off as greyscale or photoopying it to see that the tones are sufficiently distinct. I was thrilled today to discover your site. It allows (I assume) somewhat more accurate checks and, best of all, it suggests that my 'shades of grey' theory was reasonable for the time.

Daltonized artworks

Examples of famous works of art after the application of the Daltonize algorithm.

The aim was to alter the color balance to bring out details that would normally be hidden to dichromats. The Daltonize algorithm attempts to do this in such a was as to maintain the same overall look and feel of the image. In most cases, dichromats will see a difference between the original image and the Daltonized version.

Four images are presented on each page. These are the 1: original image, 2: a simulation of the original image as seen by a dichromat, 3: the Daltonized version of the original image and 4: a simulation of the Daltonized image as viewed by a dichromat. By comparing images 2 and 4, it is possible for subjects with normal color vision to appreciate the difference that the Daltonize algorithm makes.
