Import a theme file into Ghidra

\n

Ghidra has supported UI themes since version 10.3.

\n

Reference: Ghidra What’s New

\n

This has made font and color settings dramatically more convenient than before.

\n

For Ghidra UI themes, you can either customize one of the built-in themes or use a theme published by the community.

\n

There are still not that many community themes available, but among the public options, I recommend the themes in the following repository.

\n

Reference: lr-m/ghidra-themes: A collection of themes for Ghidra to make long hours of reverse-engineering even more enjoyable!

\n

Setting a theme is simple: just import the file from the Ghidra GUI after launching it.

\n

\n

If you want to change the selected theme, you can do so from Switch.

Customize fonts and colors in a Ghidra theme

\n

In the current release, you can easily customize a Ghidra theme from the GUI by selecting [Edit] > [Theme] > [Configure].

\n

Another very convenient point is that settings changed from the GUI are previewed in real time even if you do not click [Save] (if I remember correctly, before the current theme feature was released, checking theme changes was fairly cumbersome).

\n

\n \n \n \n \n \n \n \n \n

\n

Personally, I think the easiest approach is to confirm the settings here and then add them to a theme file when making edits.

\n

Customize fonts

\n

Ghidra fonts can be customized from the Fonts tab.

\n

There seem to be mainly two formats for the setting values.

\n
    \n
  1. Direct specification
    2. \n
\n
<font name>-<style>-<size>
\n
    \n
  1. Common label
    2. \n
\n
[font.monospaced]

For example, in the icicle theme I am currently using, you can see that the color.icicle.GreenBlue color palette is used for comment sections in various windows.

\n

\n

This time, I will change a few colors in the icicle theme.

\n

I think the icicle theme is excellent, but for example, it uses Black for the Entry Point color, so there are places where the text blends into the background and becomes hard to read.

\n

\n

Even simply replacing that with color.icicle.BlueViolet, for example, makes it dramatically easier to read.

Install fonts on Windows

\n

On Windows, you can add fonts by installing the .ttf files you downloaded from [Personalization] > [Fonts] in the Settings app.

\n

\n

Adding them is very easy: just drag and drop the .ttf files into the Settings app.

Install fonts on Ubuntu

\n

On Ubuntu, you can install fonts by copying the extracted ttf files to /usr/local/share/fonts.

\n

This lets you configure fonts such as Roboto Mono in Ghidra on Ubuntu as well.
