high-contrast media feature

Cynthia,

I am reviewing CSS Media Queries Level 4 for APA.   Issue 2  Using this
media feature for accessibility purposes overlaps a lot with the
high-contrast media feature proposed by Microsoft. Can we adjust this so
that it covers all use cases for both, or somehow modify them to work in an
orthogonal, rather than overlapping, fashion?

APA may wish to support a high-contrast media feature, but the proposed
high-contrast media feature is not included in the document. Can you
provide us the proposal for the high-contrast media feature so we can weigh
in? The proposed light-level media feature does not tell whether a user is
using a high contrast mode (black background/white text, white
background/black text) which many apps would like to know so they can
adjust the UI accordingly. Icon colors, charts and custom controls would
benefit from knowing whether the user is in a black background/white text
mode or not.
                                                              
     Regards,
