확장 가능한 '이중 테두리'-직사각형

Question

8개(내부 4개, 외부 4개) 테두리 각각에 대한 색상을 별도로 지정할 수 있고 크기를 조정할 때 외부 직사각형과 내부 직사각형 사이의 분리 공간을 넓히지 않는 '이중 테두리'가 있는 직사각형을 어떻게 그릴 수 있습니까? ㅏ resizebox?

(죄송합니다. 저는 TikZ를 처음 접했습니다.)

다음을 시도했지만 단점은 3개의 '직사각형'(내부 테두리가 외부 테두리와 같음)이며 가장자리가 '연결되지 않은' 것처럼 보입니다.

\begin{tikzpicture}
  \draw[red, double = black] (0,0) -- (1,0);
  \draw[green, double = purple] (1,0) -- (1,1);
  \draw[blue, double = brown] (1,1) -- (0,1);
  \draw[yellow, double = white] (0,1) -- (0,0);
\end{tikzpicture}

아마도 그거?
