Admin's "no" icon is incorrect and should be replaced

[Daniele Procida]

The admin uses pretty yes/no icons:

• yes, ​https://github.com/django/django/blob/master/django/contrib/admin/static/admin/img/icon-yes.gif, which displays as
• no, ​https://github.com/django/django/blob/master/django/contrib/admin/static/admin/img/icon-no.gif, which displays as

The "no" icon is incorrect; means "no entry", not "no".

This leads to some confusing interface cases: a boolean field called "locked" or "restricted" for example, will show a no entry sign when an item is not locked or restricted - the sign itself denotes restricted access to something.

While the "yes" tick is commonly-recognised, there is no good symbol for "no" - most negative symbols denote prohibition, and I can't think of any that imply simple negation.

Even a red cross in a box [x] isn't adequate, because crosses are also used to check boxes in many interfaces, and some people are red-green colourblind.

My suggestion is to change both symbols, so that "yes" is a green tick in a green box, and and "no" is an unticked red box.

Could you raise this as part of the work elky is doing on the "new look"? ​https://groups.google.com/d/msg/django-developers/HJAikaEBqJ4/L6pU8iIi6uMJ

As this change will require updating the documentation screenshots in ref/contrib/admin/index.txt and intro/tutorial02.txt, it seems like a good opportunity to combine efforts.

I've raised it there - ​https://github.com/elky/django-flat-theme/issues/3 - but I don't think it should depend on that (what if that project stalls, for example?).

I expect it will be merged in a matter of weeks. If not, I'll consider reopening this ticket. I'd rather not create conflicts/duplicated effort by leaving this open and tempting someone to pick it up now.
