+.SS Note on \f[CR]color\-scheme\f[R]
+By default, the browser\(cqs chosen \f[CR]color\-scheme\f[R] (either
+\f[CR]light\f[R] or \f[CR]dark\f[R]) will affect the color of various
+unstyled elements like input fields, which are generally only applicable
+if your document is specifically targeting HTML.
+.PP
+By default, Pandoc emits \f[CR]color\-scheme: light dark\f[R] to allow
+the system to choose between a default light\-mode or dark\-mode scheme,
+but it alters this if variables specifically override colors, under the
+assumption that the user wishes for that scheme to always be used.
+.PP
+Currently, this is only per a basic heuristic that checks whether the
+following variables are provided:
+.IP \(bu 2
+\f[CR]fontcolor\f[R]
+.IP \(bu 2
+\f[CR]fontcolordark\f[R]
+.IP \(bu 2
+\f[CR]backgroundcolor\f[R]
+.IP \(bu 2
+\f[CR]backgroundcolordark\f[R]
+.PP
+And if only one \(lqmode\(rq is provided (light or dark),
+\f[CR]color\-scheme\f[R] is set so that this chosen mode is used always,
+regardless of the system\(cqs preference for light or dark mode.
+.PP
+Note that there are a few caveats to this, namely that:
+.IP \(bu 2
+If the browser does not support \f[CR]light\-dark\f[R] (older than
+\(ti2024), then it will always choose light mode, regardless of this
+override.
+.IP \(bu 2
+When printing, light mode is always chosen, and color variables are
+ignored.
+.IP \(bu 2
+Syntax highlighting is currently unaffected by color scheme.
+.PP
+In general, if you wish to override the theming for a single scheme, you
+should choose to override either the normal \f[CR]*color\f[R] variables
+(light mode) or the \f[CR]*colordark\f[R] variables (dark mode) to
+ensure that the styles do not conflict with other styles added by new
+versions of Pandoc or the browser itself.
