I drawed the following torus using Tikz:

[![](https://i.stack.imgur.com/6qJY7.png)](https://i.stack.imgur.com/6qJY7.png)

```
\begin{tikzpicture}
\fill[blue] (7.5,0) ellipse (1 and .75);
\draw (7.5,0) ellipse (1 and .75);
\begin{scope}
  \clip (7.5,-.9) ellipse (1 and 1.25);
  \draw (7.5,1.1) ellipse (1 and 1.25);
\end{scope}
\begin{scope}
  \clip (7.5,1.1) ellipse (1 and 1.25);
  \draw (7.5,-1.1) ellipse (1 and 1.25);
\end{scope}
\end{tikzpicture}

```

I want to color the middle of it white, so it can really look like a torus. How could I do it?
