+% as the book is printed in two colors only (black and blue) we need
+% to ensure that other colors are replaced by gray if necessary:
+
+\AtBeginDocument{
+\ifx\color\@undefined
+\else
+\definecolor{red}{gray}{.7}
+\definecolor{green}{gray}{.8} % we keep green
+\definecolor{yellow}{gray}{.9}
+\fi

+
+% for margin rules in math examples we need color to make them
+% blue. So in this class color is actually always present:
+
+\RequirePackage{color}
+
+\newcommand \EX@rulewidth {0.25pt}
+
+%% Keep on hacking!
+\newcommand \SetupMarginLines{%
+ \AtBeginDocument
+ {\hbox\bgroup \kern-\EX@rulewidth

+ \vbox\bgroup}%
+ \AtEndDocument

+ {\color{blue}\vrule width \EX@rulewidth}%
+ \kern-\EX@rulewidth \egroup}%
+}
