不同颜色的树的孩子

Question

如何修改此 tikz 代码片段中任意节点的颜色？

\begin{tikzpicture}[sibling distance=3em, every node/.style = { rounded corners, draw, 
 align=right, top color=white, bottom color=blue!30}]] 
 \node {000} 
  child { node {000}}
  child { node {100}} 
  child { node {010}}
  child { node {001}
     child { node {000}
         child { node {000}} 
         child { node {100}}
         child { node {010}}
         child { node {001}}
         child { node {110}}
         child { node {011}}
         child { node {101}}
         child { node {111}} } 
     child { node {100}} 
     child { node {010}} 
     child { node {001}}
     child { node {101}} 
     child { node {011}}
     child { node {110}} 
     child { node {111}} }
 child { node {101}} 
 child { node {011}}
 child { node {110}}
 child { node {111}};
\end{tikzpicture}

我不太明白你的意思。不过，我为你做了这个小修改。

\documentclass{standalone}

\usepackage{tikz}
\begin{document}

\tikzset{
stdNode/.style={rounded corners, draw, align=right},
greenRed/.style={stdNode, top color=green, bottom color=red},
blueRed/.style={stdNode, top color=blue, bottom color=red}
}


\begin{tikzpicture}[sibling distance=3em, every node/.style={rounded corners, draw, align=right, top color=white, bottom color=blue!30}]] 
 \node {000} 
  child { node[red] {000}}
  child { node[top color=green,bottom color=red!30] {100}} 
  child { node[greenRed] {010}}
  child { node[blueRed] {001}
     child { node {000}
         child { node {000}} 
         child { node {100}}
         child { node {010}}
         child { node {001}}
         child { node {110}}
         child { node {011}}
         child { node {101}}
         child { node {111}} } 
     child { node {100}} 
     child { node {010}} 
     child { node {001}}
     child { node {101}} 
     child { node {011}}
     child { node {110}} 
     child { node {111}} }
 child { node {101}} 
 child { node {011}}
 child { node {110}}
 child { node {111}};
\end{tikzpicture}

\end{document}

我强烈推荐手册.pdf在https://ctan.org/pkg/pgf。

仅仅因为一个人可以选择这些奇怪的颜色并不意味着他应该这样做。
