UAs may further tweak these <a>forced colors mode</a> heuristics
to provide better user experience.

<div class="example">
Authors may still use features such as ''color-mix()'' in [=forced colors mode=].
In such cases, the [=computed value=] will behave as it would normally,
but the [=used value=] will be overridden with an appropriate [=system color=].

<pre highlight=css>
.example {
color: color-mix(in srgb, CanvasText, Canvas);
}
</pre>

The [=computed value=] for 'color' will be a 50-50 blend of the ''CanvasText'' and ''Canvas'' [=system colors=].
That value will inherit to descendants and be observable via APIs such as {{Element/computedStyleMap()}}.

The [=used value=] for 'color' will be a system color chosen by the UA, for example ''CanvasText''.
</div>
