forced-color-adjust

The forced-color-adjust CSS property allows authors to opt certain elements out of forced colors mode. This then restores the control of those values to CSS.

Syntax

css
forced-color-adjust: auto;
forced-color-adjust: none;

/* Global values */
forced-color-adjust: inherit;
forced-color-adjust: initial;
forced-color-adjust: revert;
forced-color-adjust: revert-layer;
forced-color-adjust: unset;

The forced-color-adjust property's value must be one of the following keywords.

Values

auto

The element's colors are adjusted by the user agent in forced colors mode. This is the default.

none

The element's colors are not automatically adjusted by the user agent in forced colors mode.

Usage notes

This property should only be used to makes changes that will support a user's color and contrast requirements. For example, if you become aware that the color optimizations made by the user agent result in a poor experience when in a high contrast or dark mode. Using this property would enable tweaking of the result in that mode to provide a better experience. It should not be used to prevent user choices being respected.

Examples

Preserving colors

In the example below the first box will use the color scheme that the user has set. For example in Windows High Contrast mode black scheme it will have a black background and white text. The second box will preserve the site colors set on the .box class.

By using the forced-colors media feature you could add any other optimizations for forced color mode alongside the forced-color-adjust property.

CSS

css
.box {
  border: 5px solid grey;
  background-color: #ccc;
  width: 300px;
  margin: 20px;
  padding: 10px;
}

@media (forced-colors: active) {
  .forced {
    forced-color-adjust: none;
  }
}

HTML

html
<div class="box">
  <p>This is a box which should use your color preferences.</p>
</div>

<div class="box forced">
  <p>This is a box which should stay the colors set by the site.</p>
</div>

Result

The following screenshot shows the image above in Windows High Contrast Mode:

The example above in high contrast mode shows the first box with a black background the second with the grey background of the CSS.
