# 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 Colors](https://1926493584-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FD7fgl4EL0WWJ18ZQcIxE%2Fuploads%2Fgit-blob-4564be1658adb483118e5ef7eb38374bcf097403%2Fcolors.png?alt=media)

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:

![Windows 11 style tabular view selection](https://1926493584-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FD7fgl4EL0WWJ18ZQcIxE%2Fuploads%2Fgit-blob-7032981bf42bed88c017f39898b122a384b59635%2Fwindows11_contrast.png?alt=media)

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:

![Fusion style tabular view selection](https://1926493584-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FD7fgl4EL0WWJ18ZQcIxE%2Fuploads%2Fgit-blob-54b2aa9097b8aaa029da9fc40b625970b2959d10%2Ffusion_contrast.png?alt=media)

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`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
