A color-blind user posted a feature-request on our English.SE site, asking for non-color-based visual cues to help distinguish the Meta site from the Main site.
I think it is an excellent request to accommodate users with poor color vision. Some of the suggestions on that user's request included
- Making the "meta" more prominent in the title
- Changing the question/answer separators
- Changing the border around the question title
We haven't heard anything back about this feature request on our site, but it seems this would be helpful on the other SE sites as well.
And Robert Harvey, yes, actually, it would be helpful if ours were prominent, like on this site. Ours looks like this:
which is pretty identical to the main:
except for the coloration and a weensy "meta" that can be easily overlooked if you can't see reds well. This is how the headers look to a red-green color-blind person, courtesy of http://colorfilter.wickline.org/ :
And this is how they look in greyscale:
Making it blink would be unnecessary.
Programmers, TeX, and Apple also have very similar Main and Meta banners, for instance (I think the TeX sites are particularly difficult to distinguish).
