Adds an option to simulate different color schemes allowing you to test <a data-l10n-name="mdn-preferscolorscheme">@prefers-color-scheme</a> media queries. Using this media query lets your stylesheet respond to whether the user prefers a light or dark user interface. This feature lets you test your code without having to change settings in your browser (or operating system, if the browser follows a system-wide color scheme setting). See <a data-l10n-name="bugzilla1">bug 1550804</a> and <a data-l10n-name="bugzilla2">bug 1137699</a> for more details.
