我想将页脚的三个部分修改为不同的颜色。如何实现?这里,我的页脚有三个部分。
\documentclass[10pt,xcolor={dvipsnames}]{beamer}
\usefonttheme{professionalfonts}
\useoutertheme{infolines}
\mode<presentation> {
\usetheme{Frankfurt}
\usecolortheme{whale}
\setbeamercolor{section in head/foot}{bg=blue!0!black,fg=white}
% -------------------------------------------------------------------------------------------------------------------------------------
% footer
%\setbeamercolor{section in foot}{fg=white, bg=OliveGreen}
%\setbeamercolor{section in foot}{fg=white, bg=MidnightBlue}
\setbeamerfont{footline}{size=\fontsize{6}{6}\selectfont}
%\setbeamercolor{section in foot}{fg=white, bg=ForestGreen}
%\setbeamercolor{section in foot}{bg=blue!40!black,fg=white}
\setbeamercolor{section in foot}{fg=white, bg=BlueViolet}
\setbeamertemplate{footline}
{
\hbox{%
\begin{beamercolorbox}[wd=.25\paperwidth,ht=2.6ex,dp=1ex,center]{section in foot}%
