你能帮我解决这个问题吗？
- 我需要在所有幻灯片的部分栏（顶部）中使用深红色的背景颜色。
- 我需要在所有幻灯片上的部分栏正下方添加一条狭窄的深蓝色栏。
- 幻灯片底部不应显示任何内容（无作者姓名、无章节等）
- 所有文字均应为黑色。
这是我的简化的乳胶代码：

我需要在所有幻灯片的部分栏（顶部）中使用深红色的背景颜色。
\setbeamercolor{section in head/foot}{bg=red!50!black}我需要在所有幻灯片上的部分栏正下方添加一条狭窄的深蓝色栏。
您选择了一个相当复杂的主题，标题元素之间有颜色阴影。但也许这些颜色过渡可以用于您的彩色条。
幻灯片底部不应显示任何内容（无作者姓名、无章节等）
\setbeamertemplate{footline}{}所有文字均应为黑色。
\setbeamercolor{title}{fg=black} \setbeamercolor{frametitle}{fg=black, bg=white}
\documentclass[compress,black]{beamer}
\usetheme{Szeged}
\useoutertheme[subsection=false]{smoothbars}
% - I need a darkred background color in the sections bar (at the top) on all slides.
\setbeamercolor{section in head/foot}{bg=red!50!black}
% - Just beneath the sections bar I need a narrow darkblue bar on all slides.
\makeatletter
\AtBeginDocument{
\usebeamerfont*{headline}
\colorlet{global.bg}{bg}
\usebeamercolor{subsection in head/foot}
\usebeamercolor{section in head/foot}
\usebeamercolor{frametitle}
\pgfdeclareverticalshading{beamer@barshade}{\the\paperwidth}{%
color(0ex)=(blue);%
color(1ex)=(blue);%
color(2ex)=(section in head/foot.bg);%
color(7ex)=(section in head/foot.bg)%
}
\pgfdeclareverticalshading{beamer@aboveframetitle}{\the\paperwidth}{%
color(0ex)=(blue);%

color(2.5ex)=(section in head/foot.bg)
}
\pgfdeclareverticalshading{beamer@belowframetitle}{\the\paperwidth}{%

color(1ex)=(frametitle.bg)
}
}
\makeatother
% - Nothing should be displayed on the bottom bar of the slides (no authorname, no section, etc)
\setbeamertemplate{footline}{}
% - All text should be in black.
\setbeamercolor{title}{fg=black}
\setbeamercolor{frametitle}{fg=black, bg=white}
