如何用不同的颜色绘制不同的线条？

答案1

您可以\ifodd在柜台上使用测试FancyVerbLine。将下面的代码片段放在\makeatletter和之间\makeatother。

\renewcommand{\theFancyVerbLine}{%
    \ifodd\c@FancyVerbLine%
        \sffamily\textcolor[rgb]{0.5,0.5,1.0}{\scriptsize\oldstylenums{\arabic{FancyVerbLine}}}%
    \else%
        \sffamily\textcolor[rgb]{1.0,0.5,0.5}{\scriptsize\oldstylenums{\arabic{FancyVerbLine}}}%
    \fi%
}
