20. Colour combinations - from hgrebdes

It has long been recognised that the reading ability of many dyslexic individuals is increased (or at least the visual stress decreased) by changing background colours both for paper and computer screens. However, there are few opportunities to experiment with their preferences beyond a few preset choices. Furthermore, the preference may depend on the font and size for which the alternatives are usually restricted.

The website below allows all the variables to be changed, though the number of word in the test area is a little limited.
