Re: [csswg-drafts] [mediaqueries-5] Remove (prefers-contrast) as a boolean, and replaced by a new color reduction media query (#6036)

All forced colors scenarios do require reduced color complexity, and I would be happy to try to convince you of that :)

## First, a technical reason: 

Because you only have a handful of colors at your disposal, all types of gradients and box shadows are out, irrespective of the colors that the user chose for the theme.

## Secondly, a practical use case:

To give you an idea of what a fully-fleshed forced-colors mode that is not high contrast can result into, here is for instance what Outlook looks like using a "Reduced complexity (light blue)" theme, whose purpose is to limit color usage on the screen, and have all "interactive things" be blue, so that it is easy to see at a glance what is clickable on an user interface:

As you can see, while this theme I presented does not match a "high contrast" criteria because of the dark on light gray, achieving this end result still required a reduced color complexity, for things to work properly.

Just in case this needs some context, this is what a page looks like in this forced-colors mode versus not:

<table><tr><td>

</td><td>

</td></tr></table>

As your can see, irrespective of the choice of colors, the use of gradients and visual complexity has been reduced, to achieve the desired effect.
