Re: [w3c/manifest] Add support for defining a theme color for both light & dark modes (prefers color scheme) (#975)

dmurph left a comment (w3c/manifest#975)

Ah.... author defined precedence - Sorry I missed that part. That's definitely another option. The main difficulty there, I believe, is merging the old and new icon types in one list, as the old list's behavior is the opposite for Chromium - we use the 'last' appropriate one we find, not the first. I don't think it's impossible to change this behavior - we would want to likely inspect the all of the manifests of the top X installed PWA sites to make sure that this wouldn't cause problems - but yeah. Another change.

There are sooooo many ideas here, I worry about this conversation never ending.

What can we agree on that will have impact? what about just the theme & background colors?

@marcoscaceres had this suggestion above I think - What do we all think about this? This seems fine to me:

```json
  "color_scheme_dark": {
    "theme_color": "#5f7995",
    "background_color": "#ff7ff5"
  }
```

Maybe we can agree on this part, and move the icon discussion to another thread?
