我试图制作一份包含彩色球体的报表，该报表应包含在命令中并动态更新。我定义了一个彩色球体，它接收颜色、值和文本。颜色由值确定，我使用一系列 ifthen 进行选择。问题是我无法让球体接受带有颜色参考的字符串。

答案1
我认为最简单的方法可能是定义一个颜色newcol，然后对其进行适当的设置。这可以避免在实际测试时尝试处理颜色设置所导致的问题。
稍微简化一下这个例子：
\documentclass{article}
\usepackage{tikz}
\usepackage{ifthen}
\definecolor{newgreen}{RGB}{173,194,0}
\definecolor{neworange}{RGB}{217,109,0}
\definecolor{newyellow}{RGB}{239,186,0}
\definecolor{newred}{RGB}{180,30,10}
\definecolor{newgrey}{RGB}{77,77,77}
\colorlet{newcol}{black}
\begin{document}
%%% Here we make colored sphere %%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newcommand{\gradientcircle}[3]{%
\pgfdeclareradialshading{ballshading}%
{\pgfpoint{-10bp}{10bp}}{%
color(0bp)=(#1!45!white);%
color(9bp)=(#1!75!white);%
color(18bp)=(#1!70!black);%
color(25bp)=(#1!50!black);%
color(50bp)=(#1!15!black)}%
\begin{tikzpicture}%
\pgfpathcircle{\pgfpoint{0cm}{0cm}}{1.25cm}%
\pgfshadepath{ballshading}{280}%
\pgfusepath{}%
\node{\textbf{\textcolor{newgrey!5!white}{\Huge#2}}};%
\end{tikzpicture}\par\smallskip%
{\scriptsize #3}%
}
\def\thresholdi{50}
\def\thresholdii{75}
\def\thresholdiii{90}
\newcommand{\TestColor}[1]{%
\ifthenelse{\NOT#1=0}{%

\ifthenelse{#1>\thresholdii}{%

但是，有比使用更简单的测试方法ifthen。例如，您可以使用 PGF/TikZ 本身来处理这些内容，因为无论如何您都会加载它。（但我想我更可能使用 TeX 的东西。我从来都不喜欢 LaTeX 等价物的笨拙，尽管我猜它们更安全。）
