# SetColors

## Description

Setup colors. The IDA Colors dialog lets you change the active theme or fine-tune the one currently in use. Each tab lets you customize specific parts of the UI.

IDA keeps the color configuration in the registry. There are 3 predefined schemes. The user can modify the existing schemes or add his own schemes. New schemes should be added to the "themes" subdirectory in IDA.

### Windows 11 style contrast

By default, IDA uses the "out-of-the-box" Qt style - named `windows11`.

That style mimics the core Microsoft Windows 11 theme, with which some users have reported some discomfort due to low-contrast hints.

This is observable especially in "tabular" widgets, where the selection painted using an somewhat discrete overlay:

Addressing this naïvely (e.g., by overriding the selection entries through CSS) might do more harm than good though, so we have decided against that.

Instead, we recommend using the Qt "Fusion" style, which offers significantly better contrast:

This is achievable by [opening the "Environment variables" dialog](https://learn.microsoft.com/en-us/windows/win32/procthread/environment-variables), and adding an entry called `QT_STYLE_OVERRIDE` with the value `fusion`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hex-rays.com/ida-9.3/ida-actions/setcolors.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
