If you're using an interface that supports LaTeX output, such as a Jupyter notebook:

```
sage: show(["1", LatexExpr(r"{\color{red} 2}"), "3"])
```

$$\displaystyle \left[1, {\color{red} 2}, 3\right]$$

To automate it, you could do e.g.

```
sage: show([LatexExpr(r"{\color{red} " + x + "}") if x == "2" else x for x in L])
```

or

```
sage: show([LatexExpr(r"{\color{red} " + x + "}") if k == 1 else x for k, x in enumerate(L)])
```

If you're using an interface that supports LaTeX output, such as a Jupyter notebook:

```
sage: show(["1", LatexExpr(r"{\color{red} 2}"), "3"])
```

$$\displaystyle \left[1, {\color{red} 2}, 3\right]$$

To automate it, you could do e.g.

`sage: show([LatexExpr(r"{\color{red} " + `~~x ~~latex(x) + "}") if x == "2" else x for x in L])

or

`sage: show([LatexExpr(r"{\color{red} " + `~~x ~~latex(x) + "}") if k == 1 else x for k, x in enumerate(L)])
