Thanks for the feedback Tom.
I've implemented your suggestion:
https://github.com/quinox/jenkins/commit/78d222c607d31bdcfd5df7c20dbefe3ec937f3de
The differences for most people will be subtle, instead of #333-on-white you get <default text color (#000)>-on-white. You shouldn't see any other changes. For me the change is significant, I get usable input fields again.
I looked at a few CSS frameworks yesterday, some follow the road of color-style-everything (fe. Bootstrap) while others don't color-style input elements at all (fe. Yahoo!'s Pure CSS)
Caused by commit 143581e67fbcf971bfdadf2ad42535a6912caf73 which relates to
JENKINS-24625.I don't think explicitly setting the background-color is the answer to
JENKINS-24625.
