    Colour combinations (2002)

    There is a certain two colour combination that, apparently, shouldn't be used - it can affect people with epilepsy? Does someone remember what they are?

    Is there other general advice (about fonts, etc.) for people with dyslexia, learning difficulties? Thanks, Andy.

    Hi Andy

    I am not sure where you live but can only advise you on a <img src=/S/flags/UK.gif border=0 alt=UK width=30 height=18> perspective. I am talking from a web background but you should treat a dyslexic the same as you would a person with visual impairment, apparently the ratio of dyslexics to visually impaired is a staggering 3:1. Dyslexics benefit from high contrast as would a visually impaired person. I have found a link to the Royal National Institute for the Blind in the <img src=/S/flags/UK.gif border=0 alt=UK width=30 height=18> whch discusses this and advises.

    Thank you. As I recall there is a combination of, perhaps, red and blue to which epileptics are susceptible.. Does anyone recall this? Andy.

    Yes, I would say so. Have look here also about Visual Acuity and contrast. There are suggestions in section 6 for colour contrasts and dyslexics

    Avoid red/green, orange/blue, and red/blue. If you are presenting to people with epilepsy avoid all slide transitions and animations. Good references: http://www.springerlink.com/content/lr5ybtwm059jdmvr/ and http://www.indezine.com/ideas/prescolors.html and http://www.uwgb.edu/newpart/PDF/IntrotoPP.pdf

    Re: Colour combinations (2002)

    The colors you are thinking of are red and blue, but especially red. See the article here for more information:
    http://www.epilepsyfoundation.org/epilepsy...ity20060306.cfm

    Note that the article places far more emphasis on triggers such as flashing light, so you might also want to watch whatever animation/transitions you have in your presentation.

    That is interesting about red, I created a website for a school which had a red banner image , white writing and a small logo on it. I was showing it to my students as I was discussing how the page was constructed using CSS. I left it on the screen (4 metres x 4 metres) and got them to get on with their work. My assistant for the night (another lecturer) came up to me and asked if I could turn the screen off as it was making him feel sick. I asked what was wrong and apparently he is colour blind and when he sees deep reds on a screen it "flashes" at him, on, off, on, off and it makes him feel ill. He has no other impairment that he knows of, just this visual apparition.

    Wow--that is interesting. What I've always found fascinating is the effect that different colors have on people, such as the color red makes you hungry, yellow makes babies cry, etc--but I didn't realize that color blind people were affected by color differently--I just thought they couldn't see them <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
