Here's a screenshot of how high-contrast mode breaks the in-browser PDF display for me (Firefox 60.5.1 ESR in Gentoo GNU/Linux). Both the buttons and the document text are hard to read.
User Agent: Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130215130331 Steps to reproduce: Opended a PDF document. Seems to be all PDF off the web that aren't scanned images affected. System has high contrast setting enabled. Background text would be black and foreground green even if it was not set. Actual results: Tried to render with green text overstamped on black text on white background, resulting in completely unreadable text. Expected results: Either apply user-selected colors or don't. Never mix and match.

Reproduces identically on Linux x64. Resetting platform to all.
OS: Windows 7 → All
Hardware: x86 → All
It seems for me that every pdf that has a text layer has a very similar problem that the text is displayed twice (i.e. the hiddel layer is rendered like a drop shadow). E.g. http://people.mozilla.org/~jdaggett/css3fontspresentation.pdf displays nearly unreadable while https://www.mozilla.org/foundation/donate_form.pdf is just fine in black on white high contrast (Win8).
From the duplicate bug 1071504 comment 6:
That's not a double rendering -- that's a text layer for the selection and highlight operation. For some reason CSS styles to hide it are disabled in the high contrast mode.

Yeah, that's because we don't honor color for high contrast, but we should probably respect transparent, as we do for backgrounds...

PDFJS uses it, for example to allow text selection. It's not great if it shows
on top of the actual PDF :-)
