Better color themes for LaTeX

Currently, none of VS Code's color themes seem to fully support LaTeX syntax. 😕

The Wiki explains it as follows Thus, you can modify the color theme on your own.

Customizing a Color Theme - FAQ

Purpose 🚀

The purpose of the discussion here is twofold.

• Present your color theme customization to support LaTeX syntax.
• Exchange information on color themes that support LaTeX syntax.

Knowing better customization is one of the important objectives. Since different ideas lead to different customizations, it will be beneficial for many people if many patterns are accumulated here.

Presenting a color theme customization

Caution ⚠️

• Customization of color themes may include color changes not intended by the author.
• Customization may not be what you expect depending on the version.

Requirements for submissions 📝

If you are willing to present a color theme customization, please mention the following.

• Color theme to be used
• Changes resulting from customization
• settings.json of customization
• Screenshots before and after customization (optional)

I look forward to seeing examples of various customizations presented. 😆
Some niche customization is acceptable. It will surely be useful to someone.

I like and use Dark+ (default dark), but I don't like the following in LaTeX syntax.

• Colors {}, () and [] in the math environment.
• In $ ... $, $ and characters within inline math are the same color.
• Some math commands such as \frac are the same color as the characters in the formula.
• In math environment, _ and ^ are the same color as characters in the formula.
• The color of label names in \ref and \label is different.

I eliminated these problems by configuring the following settings.

settings.json

    "workbench.colorTheme": "Default Dark+",
    "editor.tokenColorCustomizations": {
      "[Default Dark+]": {
        "textMateRules": [

Riemann zeta function:

\begin{equation}
  \zeta(s)
    = \sum_{n=1}^{\infty} \frac{1}{n^s}
    \label{eqn:zeta}
\end{equation}

When eq.~\ref{eqn:zeta} is $ s=2 $,
$ \zeta(s)\vert_{s=2} = \frac{\pi^2}{6} $.
