    Color Blindness

    I have perfect eyesight, which is a problem for me; I can't tell if color blind people can see my text, so can someone please tell me if the text in this screeny looks OK?

    Thanks & Regards, Jonnie

    Im not sure but it is either section 508 or AAA use a one of their validators that test for the colour i think but no validator is as good as a human.

    And i would say it is readable.

    Color blind tests
    Keep grayscale contrast as high as possible, yours is on the limit.

    OK, I was getting a bit worried. From that site, as you say Fang, I think I am on the limit so to be safe I think I might look into changing the colors a bit.

    if you can distinguish between grays, it is most likely that even a person with full blown color blindness will be able to as well, if not better than yourself.

    check out some of the tools in my dmoz section: http://dmoz.org/Computers/Internet/W...Accessibility/
    I think there are a few links which actually do full page tests in different deficiencies.

    I hope it would not be considered as spamming, if I add some resources here:

    For example about 8% of men and a few women are colour blind."

    A large quantity of spam posts were removed yesterday from the forums using a mass prune. this has left responses to those posts appearing to be addressed to the wrong people, and this is in fact what has happened here. Go ahead and list any resources you want.

    incidentally welcome back webnauts.

    Thumbs up Great!

    Thanks Dave. I think I must get a bit more active here. I see that our co-members here are concerned about accessibility and therefore I will definetely do my best to support them.

    Hopefully we can stimulate more interest among the people in the javascript forum, but maybe that's asking too much... other than that most people are fairly considerate of other users.

    I've added a few of your links to my dmoz category, I hope you don't mind.
