Description Brian 2004-10-25 13:17:36 UTC
The color scheme in comparing Differences Between Revisions is very difficult
for color blind folks.  The red text on top of, what appears to be a peach-like
color on the left is hard, as well as the red on green on the right.  I myself
am [[Color Blind]], as well as 10% of males!  If we could fix this with colors
that are easier to distinguish, preferably chosen from a web-safe pallet, it
would make this tool available to more people, and be wonderful :)  If you need
a test-monkey just hit me up on AIM: BReflection or E-mail: reflection@gmail.com

Comment 1 Tom Gilder 2004-10-25 22:25:20 UTC
We shouldn't simply show changes in colour; differences should be marked up using 
<ins> and <del> and styled with something as well as colour. Italics? Bold? Not sure.
..
Comment 2 Matthew "mpt" Thomas 2004-10-26 01:27:07 UTC
Once the HTML includes <ins> and <del> like it should:
ins, del {color: maroon; background-color: inherit;}
ins {font-weight: bold;}
del {text-decoration: line-through;}

In the meantime, to achieve the same in graphical browsers:
.diffchange {color: maroon; background-color: inherit;}
.diff-deletedline .diffchange {text-decoration: line-
through;}
.diff-addedline .diffchange {font-weight: bold;}
Comment 3 Tom Gilder 2004-11-23 02:01:44 UTC
I have made the difference pages on the English Wikipedia show changes in bold as well as being colored red. 
Hopefully this won't be moaned about too much and can stay :)

Will get around to modifying MediaWiki and fully fixing the accessibility issues one day...

That is an *excellent* idea.
Comment 5 Ævar Arnfjörð Bjarmason 2005-04-01 17:39:18 UTC
Supposedly fixed in HEAD.
Comment 6 Ævar Arnfjörð Bjarmason 2005-04-26 19:26:49 UTC
Just checked if it's been applied in REL1_4 and HEAD for all skins, it has,
marking it as FIXED.
