[css-color-adjust-1] accent-color in Forced Colors Mode

[alisonmaher]

It seems like we should probably add accent-color to the list of properties that are adjusted in Forced Colors Mode.

Forcing this to auto seems like the obvious choice, similar to scrollbar-color. However, what should happen if forced-color-adjust is set to none or accent-color is set to a system color? Should we ignore those and force accent-color to auto no matter what, or should we honor the adjust rules to allow author customization?

[FremyCompany]

If adjust is set to none, I don't think accent color should be reset.

But, more generally, it probably isn't necessary to do anything with this property btw because, in forced colors mode, browsers can just decide not to use the accent color in their firm control design, right ?

[alisonmaher]

@FremyCompany yeah, honoring forced-color-adjust and leaving it up to the UA in terms of how to handle accent-color in their form control design makes sense to me.

<dael> github: https://github.com//issues/5987
<dael> alisonmaher: This is around adding accent-color to prop adjusted in forced color mode. Similar to scrollbar where force to auto. Question is what should happen w/ forced color adjust. Rest of control isn't adjustable. fremy makes sense, though. Should be honored but up to UA how to apply.
<dael> alisonmaher: Does that sound good or are there other options to look at?
<dael> fantasai: If it's none we shouldn't force colors. Main q is do we force it to auto or do we allow it to be a color
<fantasai> s/color/system color/
<dael> astearns: Other opinions?
<dael> fantasai: I lean toward force to auto. Author doesn't know what system color will be and since trying to make page match colors user is comfortable with pushing to auto makes more sense
<tantek> regrets+
<dael> astearns: fremy comment seems to imply if adjustment is set to none other colors are reset?
<Rossen_> q?
<dael> fremy: Not the case. If adjust is none we should not touch property. But maybe we don't need to do anything. UA isn't forced to do anything with it. Saying it does not really matter. We can switch to auto, but easier to impl that we do nothing
<dael> fantasai: Could add a note UA could do that
<dael> fremy: Yeah
<dael> fantasai: Prop would be add a note what UA can ignore accent color in forced colors mode where it wouldn't otherwise
<dael> astearns: Add to the list but then say not really?
<nicole> what would happen with say a black and white display on an ereader
<dael> fantasai: Property value would stay at what set at. UA if and how it uses an accent color...well...we do define if ther is an accent color you have to change. So I think force to auto. This is used value time operation
<dael> fantasai: We do require if you have something desc as an accent color then the property does change it
<dael> astearns: fremy you okay force to auto?
<fantasai> nicole, that e-reader wouldn't have an accent-color, so accent-color would not have any effect
<dael> fremy: Yeah. Doesn't matter sinc can't observe as a user. Whatever is easier
<dael> astearns: Prop: Add accent color to list of properties adjusted and have it adjusted to auto
<dael> alisonmaher: Sounds right
<dael> astearns: Obj?
<dael> RESOLVED: Add accent-color to list of properties adjusted and have it adjusted to auto
