https://cs.chromium.org/chromium/src/ui/native_theme/native_theme.h?type=cs&sq=package:chromium&g=0&l=317 seems like a decent place to start - this seems like a system-wide issue, is there a bug for the context menu?

#777767 would work, if we can get UX sign-off.

Isn't this WAI though, if it's text that is disabled and therefore not actionable? I'd like to see it slightly darker, but wouldn't want to make it confusing for users if it's too dark and then looks clickable. 

Staging on kylixrd@ for Product Excellence phase.

Increase Disabled Text Contrast of Menus, Buttons, and Textfields

From the available palette, this is the closest we can get to 4 without
making the text actually look enabled.

The contrast ratio of menus and textfields go from 2.61 to 3.68 and
the contrast ratio of buttons go from 2.54 to 3.54.
