Is that an intent to have quite light gray ( #6D6D6D ) text on a yellow background? At home, my monitor has lower contrast, and I wondered whether my sight grew dimm or what. And I realized that the text is light gray.

I suggest to keep it much closer to black, if not black.

Don't want to remake the design of wiki through this jira issue, but - I'd much rather have white background. Could at least tables have white background?

Sorry for complaining all the time
But I really feel like this will improve the wiki's accesibility (esp. for users with low-contrast monitors like mine).

Thanks
