Post Revisions in 3.6

The Post Revisions are currently being overhauled for WordPress 3.6. The team responsible are at the concept stage & they’ve asked asked us to provide feedback now on their current mock-ups.

I have already raised the point elsewhere that perhaps a red/green combination isn’t the best of choices but I do think that the potential barriers here could be greatly mitigated if one of the mock-ups with strike-through (currently the favoured approach) was chosen. The screenshot below shows how these screens might be viewed by someone with the most common forum of colour blindness (protanopia).

Seems to me that the markup used could also greatly enhance accessibility here — with proper use of both the <ins> and <del> HTML tags.

Any other thoughts?
