「\color{red}で文字を赤くした後，\color{black}で文字を黒に戻す」という操作を繰り返すと，途中から\colorが正常に動作しなくなってしまいます．これを解決する方法としてどのような手立てが考えられますでしょうか？
以下に.texファイルの中身を記載し，コンパイルによって出力されたpdfを添付いたします．
（62回目以降の\color{red}から正常に動作していないようです）

要するに
{\color{red}色を付けたい部分}（\textcolor{red}{色を付けたい部分}はこれと実質的に同じです）とすればよくて、だから「{\color{red}」と「}」をそれぞれマクロにできればよいわけです。しかしマクロの定義に「{と}の均衡がとれていないもの」を書くことはできないため、（この場合に）同じように使える\begingroup、\endgroupを使います。
\newcommand{\Red}[1]{\begingroup\color{red}}
\newcommand{\Black}[1]{\endgroup}このマクロを使うと
\Red{}色を付けたい部分\Black{}と書くことができて、後で\Red{}と\Black{}を一括削除できます。
※「区切りのスペースの扱い」が厄介になるのを避けるために敢えて意味のない引数（{}）を入れています。
もう少し技巧的になりますが
\newcommand{\Red}[1]{\ifx0#1\endgroup\else\begingroup\color{red}\fi}と定義すると、
\Red1色を付けたい部分\Red0と書けます。（この場合は1や0が引数になっています。）
