quasicomputational has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-mediaqueries] prefers-color-scheme and printing ==
Spec: https://drafts.csswg.org/mediaqueries-5/#prefers-color-scheme (drive-by note: the section title is a copy-pasto)

What should the interaction of prefers-color-scheme and printing be? I'm specifically worried that 'prefers-color-scheme: dark' might naively cause printer ink worth more than the GDP of Hampshire to be used.

Some options off the top of my head, but I'm sure there are others:
* When printing, recommend (require?) that 'prefers-color-scheme: light' matches, because paper has a 'light' colour scheme. Is there such a thing as light-on-dark printing where this would be inappropriate?
* Have no preferred colour scheme when printing (a no-list of inappropriate media), or perhaps for all media except screens (a yes-list of appropriate media); queries involving prefers-color-scheme should always be false in those cases. This has a good forwards compatibility story if something else gets decided later.
