 What Vince says is interesting. the problem Jaws has is not that you
cannot use it white font black screen but that Jaws itself sees White Font
as 'selected text' and does not treat it normally.  freedom are not going to
do a fix for this it would need far more than a script. I think years ago
dolphin did have the same problem but altered it by adjusting their
software.this is what I was told by a technician who worked  for abilitynet.
FS will not do this. Lunar  allows Jaws to work in standard mode, but
although I cannot explain it technically  something less like Tutor would
not have worked what matters is that "Jaws must get a handle on it at the
right time" one suggestion made by abilitynet that I move to Outlook from
O.E and use Word as the email client using RTF was not practical it took for
ever, this they though would enable to  let Jaws work in Monochrome.. Had
the man in Sussex who had once worked for a firm of Electronics been able to
make the box he had told me he though would be simple it wouldn't have
interfered with Jaws at all, it would have been a box that affected what I
saw externally.  the switch it would have would enable to me to turn it to
black and white  or  flickswitch  other way and see colours but not h from
inside the computer. since he really worked  once for a firm of electronics
and his brother in law was a very nice hospital driver that is how we were
introduced. Now hadhe said at some time" I cannot do it" I would have
accepted  it. He didnot I even got as far as phoning freedon in St
Petersburg and asking Bryan carver how about DR Lee Hamilton dropping a hint
this way seemed to me from looking at the Corporate lineup of Fs DR Hamilton
was ideally suited. Bryan carver  did tell me he would speak to him and eric
Damery but he didnot comeback to me. I know it all sounds a bit odd but I
thought well they make the product they  should know and be clear about just
what a product can do and what it cannot.  I expect things like
non-disclosures clauses  come in  somewhere down the line .. As for
Hexadecimals I don't understand. I expect there many thousands of colours in
nature in fact I know there but why are they measured in Hexadecimals in
Computers.  I think from my point of view I just have to accept that you
techy's know all about and I the layman  had best accept it andnot attempt
to delve into  it, since I cannot do decimals anyway  I am a lost cause.

Hi Dorothy,
I've sorted it now and am waiting for a response from the company.  Thanks
for your suggestions though.

   Hallo Vince I wonder what the Australian tool is you mean. I know that
at Abilitynet Robin Christopherson specialises in this field. He will talk
in terms of Hexadecimals for colours and  in the beginning I had not a clue
what he meant  being alone  and trying to learn on my own there being no
tuition available from my  Association for the Blind. I have to have  black
screen and white Font and low light or no light on to cope. I use Lunar  in
Inverse Mode to do this. There were some incompatibilities to be sorted out
and it was another  lump of software on my computer on top of Jaws and
Kurzweil, however it is bearable and before it was not.  People  just
couldn't understand unless they  actually were  sitting beside me.  I was
told 'turn the screen off for get it and so  on.  I refused to do
this.Andrew Hodgson  found a way. I had been prepared to pay a man in Sussex
who told me he had worked for a firm of Electronics. He ran a Computer
repair business. He was he said designing a box to invert the screen.  a
sort of switching box.  the switch in the middle if turned up would give
colour and view. Thing is after waiting 8 months,  it came about  we Andrew
and I realised he  was not able to do it,  or admit it. I truly would not
have minded but he seemed not able to  admit it Then when I had the Hardrive
failure it all  fell apart leavingme with  No Jaws No lunar No   no anything
no windows. He brought the equipment back and  tore off saying "I never want
to hear Jaws again" Anyway  if Robin's Position with Abilitynet  is to
Survey and  draw up reports for the BBC I should  ask him about it. dorothy.

   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
