I have met few dyslexic people and asked them about their reading style.
Some of them said that typing on black key board with white writing is easier for them, it helps them identify the shape of the letter faster than their mac (which I checked had a white-ish keyboard).
Some of them also suggested that 'Serif' fonts are better to interpret.
It's not that they cannot understand or read but, some efforts perhaps? Something that could make their load easier :)
Is there any evidence that certain color schemes are easier for dyslexic people to read?
