The text in the folder view and email list view has changed from dark
grey (RGB #1f1c1b) to a lighter grey (RGB #31363b) (checked on a
different machine running 45.4.0) with the latest version of Icedove.
This represents a change in contrast ratio from 16.5 to 11.9 for the
message list.

This low contrast text makes readability much worse, and significantly
impacting people with disabilities.  In the folder view (which has a
darker background) the ratio is worse still.

There is no preference item to reverse this change (only the message
pane display colour can be changed).

Contrast ratio has been shown to have a significant impact on speed of
comprehension (as proxied by reaction times) - e.g.
http://www.laurenscharff.com/research/agecontrast.html - so I think this
change represents a significant usability regression.

Workaround for <profile-dir>/chrome/userChrome.css:

/* Make folder pane and message pane text dark grey or black */
treechildren {
	color: #1f1c1b;
        /* color: black; */
}
