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.
