Description
The only indication that a user can not drop is a change in background color from green to red - this is not accessible since it relies on only color. We should change the icon in addition to the color.

Actually DnD is not relying on colors --- it operates with CSS classes. It is up to a designer to interpret them differently, e.g., change an icon anywhere, or even show some suggestive text when certain CSS classes are defined.

but our default css classes should be accessible. The default implementation relies on CSS background images which use only a change in color. And, we need to provide default text equivalents for those background images - see #8559

In this case isn't it better to assign the ticket to theme designers? BTW, there is a ticket #6240 to add DnD CSS classes to themes.

IIRC Nikolai made those images.... probably just need to change the red arrow to an X or a circle with a backslash.

are there waiRoles defined for states of Drag and Drop that we could emulate? we could decorate the avatar (by default a table)

I have created updated icons for nomove and nocopy. I'm not a photoshop whiz so these may need additional tweaking. I am suggesting a solid bar with a red background for nomove and an x with red background for no copy.

This still doesn't address a11y fully, does it? Since it still relies on background images only?
comment:9 Changed 12 years ago by
this patch fixes the color issue so the people who can't interpret color differences can still understand the standard icons. The rest of the a11y issue is addressed in #8559 for people with more severe vision problems who turn off images or use high contrast mode. If high contrast /no images mode is detected then we use text characters.

if these new icons are acceptable I'd like to get this checked in. green plus - copy okay red x - no copy green arrow - move okay red bar - no move

Since this is an accessibility issue I marked it as high - it would be great if this could be addressed for 1.3
