+% \subsection{Coloring math mode material}
+%
+% Coloring math mode material using \cs{color_select:nn(n)} has some restrictions
+% and often leads to spacing issues and/or poor input syntax. Avoiding generating
+% \tn{mathord} atoms whilst coloring only those parts of the input which are
+% required needs careful handling. The functionality here covers this important
+% use case.

+%     \cs{color_math:nnn} \Arg{model(s)} \Arg{value(s)} \Arg{content}
+%   \end{syntax}
+%   Works as for \cs{color_select:n(n)} but applies color only to the math mode
+%   \meta{content}. The function does not generate a group and the \meta{content}
+%   therefore retains its math atom states. Sub/superscripts are also properly
+%   handled.

+% \subsection{Math color}
+%
+% The approach here is the same as for the \LaTeXe{} \cs{mathcolor} command,

+% changes.

+% \end{macro}
+%
+% \begin{macro}{\color_math:nn}
+% \begin{macro}{\color_math:nnn}
+% \begin{macro}{\@@_math:nn}
+%   The basic set up here is relatively simple: store the current color,
+%   parse the new color as-normal, then switch color before inserting the
+%   tokens we are asked to change. The tricky part is right at the end,
+%   handling the reset.

+%     \@@_math_scan_auxi:  ,
+%     \@@_math_scan_auxii: ,
+%     \@@_math_scan_end:
+%   }
+%   The complication when changing the color back is due to the fact
+%   that the \cs{color_math:nn(n)} may be followed by \verb=^= or \verb=_=
+%   or the hidden superscript (for example \texttt{'}) and its argument may
+%   end in a \tn{mathop} in which case the sub- and superscripts may be
+%   attached as \cs{limits} instead of after the material. All cases
+%   need separate treatment. To avoid repeatedly collecting the same
+%   token, we first check for an alignment tab: assuming we don't have
+%   one of those, we can \enquote{recycle} \cs{l_peek_token} safely.
+%    \begin{macrocode}
+\cs_new_protected:Npn \@@_math_scan:w

+    \peek_remove_filler:n

+          { \@@_math_scan_auxi: }
+      }
+  }
+%    \end{macrocode}
+%   Dealing with literal |_| and |^| is easy, and as we have exactly two cases,
+%   we can hard-code this. We use a hard-coded list for limits: these are all
+%   primitives. The \cs{use_none:n} herealso removes the test token so it is
+%   left just in the right place.
+%    \begin{macrocode}
+\cs_new_protected:Npn \@@_math_scan_auxi:
+  {
+    \token_case_meaning:NnTF \l_peek_token
+      {
+        \c_math_subscript_token   { }
+        \c_math_superscript_token { }
+      }
+      { \@@_math_scripts:Nw }
+      {
+        \token_case_meaning:NnTF \l_peek_token
+          {
+            \tex_limits:D        { \tex_limits:D }
+            \tex_nolimits:D      { \tex_nolimits:D }

+  }

+% \end{macro}
+%
+% \begin{macro}{\@@_math_scripts:Nw}
+% \begin{macro}{\@@_math_script_aux:N}
+%   The tricky part of handling sub and superscripts is that we have
+%   to reset color to the one that is on the stack but reset it back
+%   to what it was before to allow for cases like
+% \begin{verbatim}
+%   \[  \color_math:n { red } { a + \sum } _ { i = 1 } ^ { n }  \]
+% \end{verbatim}
+%   Here, \TeX{} constructs a \cs{vbox} stacking subscript, summation
+%   sign, and superscript. So technically the superscript comes first
+%   and the \cs{sum} that should get colored red is the middle.
+%
+%  The approach here is to set up a brace group immediately after the 
+%  script token, then to set the color appropriately in that argument.
+%  We need an extra group to keep the color contained, and as we
+%  need to allow for an explicit closing brace in the source, the
+%  inner group also is a brace one rather than \cs{group_begin:}-based.
+%  At the end of the outer group we need to insert \cs{@@_math_scan:w}
+%  to continue the search for a second script token.
+%
+%  Notice that here we \emph{don't} need to use the math-specific
+%  color selector as we can allow the
+%  |\group_insert_after:N \@@_backend_reset:| to operate normally.
+%    \begin{macrocode}
+\cs_new_protected:Npn \@@_math_scripts:Nw #1
+  {
+    #1 
+    \c_group_begin_token
+      \c_group_begin_token
+        \seq_get:NN \g_@@_math_seq \l_@@_current_tl
+        \@@_select:N \l_@@_current_tl
+        \group_insert_after:N \c_group_end_token
+        \group_insert_after:N \@@_math_scan:w
+    \peek_remove_filler:n
+      {
+        \peek_catcode_remove:NF \c_group_begin_token
+          { \@@_math_script_aux:N }
+      }
+  }
+%    \end{macrocode}
+%   Deal with the case where we do not have an explicit brace pair in the
+%   source.
+%    \begin{macrocode}
+\cs_new_protected:Npn \@@_math_script_aux:N #1 { #1 \c_group_end_token }
