Colour vision deficiency or colour blindness affects around 10 per cent of the population. But each person varies in what colours they can see, which is why it is not “colour blindness”. So what colours are best if you want all readers to enjoy colours on your website? Colour choice is not just a matter of making it look good – it can affect the readability of text and graphics as well.
A small qualitative study looked at two websites to assess their readability and usability by people who have colour vision deficiency. The researcher analysed body text, background and links and found they had an affect on the usability of the websites. The research included designing two websites and then testing them with survey participants. The results should be read in conjunction with the methodology otherwise it won’t make sense. The conclusion section does not provide the specific outcomes.
The title of the article is, The effects of color choice in web design on the usability for individuals with color-blindness. This is a Masters theses.
