User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:63.0) Gecko/20100101 Firefox/63.0 Steps to reproduce: Open the attached file graytext_2cases.html. The expanded select list has the first item disabled, but it is still black, not gray. Actual results: The first option, which is disabled, is black, not gray in the expanded select list Expected results: The disabled item should have been gray in the expanded list. Chrome has the same problem, but Safari does not. It only appears to impact OS X, and maybe only 10.14. Windows browsers are not impacted.
Neil, do you know if this is working like that on OSX only by design?

I don't see any issue in 10.13 -- the disabled option looks grey. Perhaps this is a native theme issue in 10.14 only?
This isn't restricted to text list. The following also reproduces the issue: data:text/html,<p style="color: GrayText;">This text should be grey</p> Curious that it works in the combobox. Maybe that's because the combobox dropdown renders in the parent process?

Summary: CSS graytext gets rendered as (0,0,0) in expanded select list → CSS GrayText computes to black on macOS 10.14
That color comes from: https://searchfox.org/mozilla-central/rev/fc229ed2c78648e402a9bbd50d99b69d0e227844/widget/cocoa/nsLookAndFeel.mm#783

If we add more callers of this type, it might make sense to have two functions, GetRGBColorFromNSColor and GetRGBAColorFromNSColor, but for now it doesn't seem needed.
