Cassandra Targett commented on SOLR-8090:
-----------------------------------------
I've attached a patch that changes nearly all {{color: #c0c0c0}} entries in CSS
files to {{color: #4D4D4D}}, the exceptions being a few that have some
additional contrast on hover, which I changed to {{color: #8D8D8D}}.
I've attached some screenshots to show the difference between 7.2 and this
patch. I darkened the Collections menu items (and made the selected text
white), and changed the Args list on the Dashboard to highlight the background
of the rows instead of lightening the color.
TODO: I realized as I was uploading the patch that there are some places that
use #bbb as the color, which is also too light; I'll standardize those with
#4D4D4D also as appropriate (the Core menu is one example of this).

> Project: Solr
> Issue Type: Improvement
> Components: Admin UI
> Affects Versions: 5.3
> Reporter: Mike Mallett
> Priority: Major
> Attachments: Analysis-today.png, Analysis-withPatch.png,

> The CSS for the admin UI in 5.3.1 has the following definition which affects
> help text in a variety of places:
> #core-selector #has-no-cores span
> {
> color: #c0c0c0;
> display: block;
> }
> This is displayed on a white background, making the text with colour #c0c0c0
> next to impossible to read. This fails WCAG accessability guidelines and can
> be checked using this Contract Checker:
> http://webaim.org/resources/contrastchecker/
> Please adjust the CSS for the admin UI to display text in a more highly
> contrasted colour. Thanks.
