[bcab] Re: Accessibility considerations

well charles it may seemodd not tobe sure of my own Email address, this is due to ithaving been simple Like User @ and a few letters and digits I wanted it kept that way. However on the day in question with Tony B.RnIb Volunteer and Zen i finished up with a mouthful, all of which was not intended. It was too complicated to change and I was stuck with what was given. As the Jaws Users list had already had a job after my HD failure and george only knewme as User@ all my messages were bounced. Anyway I think it is Dorothy. Ingram-Gorban @ Zen.co.uk Give it a shot . dorothy I cannot see yours only a Website. ----- Original Message ----- From: "Charles Crisp " <charlescrisp@xxxxxxx>

Hallo Charles  I know you don't use JEW but another product. I  wonder if
you have flexibility with it. I found joining a couple of Societies helpful
Strictly speaking I do not  fit into  a particular slot.  However having
suffered severe damage to my Retina and the Pigment destroyed and the
Macular I  found the Mac Disease Society helpful and the R.P Society. Having

seeing problems in common with both. I wonder if you have done this? My
subscription is due to the MD Society I receive  their Audio tapes.  I had
interesting info in from Mary Murphet last summer.  It just occurred to me
you may  find helpful information.. .  If you  like I can send you some I
have I am not sure of your Email address. Can you see mine?  Incidentally
Andrew was very impressed with the research you sent on the Freeserve
imbedded problem.  He  has been very  hard pressed for time recently but
will try to talk me through when he can. Dorothy

Ps. I hope in France or anywhere you  wear Blue blockers. I cannot wear the
very dark ones but the lighter ones. to cut out the Blue/green end of the
Spectrum. Professor Bird believes this is most important.

Hi all

I've come late to this discussion.

One of the problems with screen colours which are fixed to any standard is
that some eye conditions are variable and one set of colour and contrast may
not suit everyone.
Someone mentioned the BBC and they have the 'My web, my way' web site at

http://www.bbc.co.uk/accessibility/

This contains advice on how to change the screen colours and contrast for
individual preference.

Perhaps it is more important to have a standard that will allow all screen
readers perform better, and we all know how difficult this can be.


Kind regards

Karen,

   You're absolutely right about the fact that many agencies are
unscrupulous about the quality of service they deliver. It's one of the many
reasons that reading PAS 78 is such a good idea:
http://www.drc-gb.org/library/website_accessibility_guidance/pas_78.aspx

   For people who are commissioning websites, but know little about web
accessibility, PAS 78 is a great place to start understanding the basics. It
even includes a checklist of questions to ask prospective agencies before
you hire them.

   Additionally, it talks about the need for ensuring that the level of
accessibility required is explicitly mentioned in the contract you have with
the agency. That way, if it comes to light at a later point that your
website is not accessible, you have legal recourse to resolve the problem.


Regards,
Léonie.

I sometimes help organisations with their websites, and sadly I know that
some of them (or more probably their web agencies) will put the
accessibility logos on their sites because they believe certain testing
tools are all they need to use, and they don't actually read the
accessibility guidelines.

Others say they are "working towards accessibility", so they say it's
cheaper for them to have the logo on the website from the start, or else
they will have to pay the agency to add it later. And others are simply
misled by their agencies completely.

Colour contrast is definitely one thing that inexperienced organisations are
surprised to hear about, so I'd suggest you contact them to explain the
issue and ask them to confirm when they will fix it, as this nudge may be
all that is needed.

What would be good is some way of publicising the names of agencies that do
mislead their clients in this respect. The odd mistake is understandable,
but what some of them get away with is outrageous. In the end their clients
are the ones who end up taking all the flack, whereas the agency is
invisible and only beholden to their client, who will have trusted them to
have (and paid for) the skills that the organisation lacked.

Hope this helps and sorry for the rant!

Karen

Karina, couldn't agree more.  The colour combination you mention sounds
ridiculous.

Contrast is indeed an issue, mentioned in many accessibility contexts.

For example, this is from w3.org's section, "Techniques For Accessibility:
Evaluation And Repair Tools"

"Checkpoint 2.2 - Ensure that foreground and background color combinations
provide sufficient contrast when viewed by someone having color deficits or
when viewed on a black and white screen "

The contrast values can indeed be tested by looking at the numbers or
numeric equivalents of names used for colors. So it's pretty easy to
auto-detect this problem.

I've used the Vision Australia Web Accessibility Toolbar for a long time.
One of the tests included there is a colour contrast test. It's not
difficult to carry this out, so really there's no excuse for getting it
wrong. It helps if you know that the red, green and blue can each range from
0 to 255, and that the hex digits for those are 00 and FF. That's about all
there is to it.

Sadly, I've come across sites put together by blind people who haven't got
it anywhere near right. One had a green background (00FF00), red text
(FF0000) and blue links (0000ff). Well, the FF digits give it away straight
away. The text would be invisible in black and white, and in colour it would
at the very least look yucky.

I don't know for sure, but I'd have thought even automated tests like
WebXact would fail pages with poor colour contrasts.

Of course, it's not as simple as that if you are designing a site for
dyslexics or people who have eye conditions like M D where they get a lot of
glare. the contrast values could be fine, but the site could be a pain to
read. I know of what I speak, believe me.

Vince.

Hi all,

I've just come across a website that claims to have WAI - AA and
WCAG 1.0 having a symbol in the corner of ths creen.  The thing that I don't
agree with is the colour contrast - white text on a light blue background.
My question is that when websites are tested by an accessibility
website/program for accessibility, is colour contrast taken into
consideration?  Surely the colour schemes to be used can be picked up from
the code.  If it isn't already taken into consideration, maybe it could be i
nthe future by specifying to the accessibility tool what is good contrast
and what is bad contrast.  Do you follow what I'm saying?  For example, if
the tool was told that white text on a light blue background was not good
contrast then it woud be able to reject websites that were accessed using
this method.

I'm interested in hearing the views of others on this topic.

Thanks.

Karina
