# Local Color Correction

Fine-tunes color, brightness, contrast, and saturation independently for three detected zones — **skin tones**, **sky**, and **vegetation**.

{% hint style="info" %}
**`Lpars.skin` targets a color range, not detected skin regions.** Warm, earthy tones like sand, desert rock, and sunset skies fall into this zone as well, not just skin. Change scene-specific adjustments within the dedicated [vScene](/features/scene-based-enhancement.md), not in the global defaults. A beach or sunrise often needs different `Lpars.skin` values than a portrait, and global values affect both equally.
{% endhint %}

## Per-zone parameters

The same five parameters are configured independently for each zone. Each zone lives in its own sub-section: `Lpars.skin`, `Lpars.sky`, `Lpars.veg`.

<table><thead><tr><th width="139.2000732421875">Parameter</th><th width="107.7999267578125">Range</th><th width="95">Default</th><th>Description</th></tr></thead><tbody><tr><td><code>strength</code></td><td>0.0 – 1.0</td><td>1.0</td><td>Overall strength of adjustments for the zone</td></tr><tr><td><code>brightness</code></td><td>-1.0 – 1.0</td><td>0.0</td><td>Brightness adjustment for the zone</td></tr><tr><td><code>contrast</code></td><td>-1.0 – 1.0</td><td>0.0</td><td>Contrast adjustment for the zone</td></tr><tr><td><code>saturation</code></td><td>-1.0 – 1.0</td><td>0.0</td><td>Saturation adjustment for the zone</td></tr><tr><td><code>huerotation</code></td><td>-10.0 – 10.0</td><td>0.0</td><td>Hue rotation for the zone</td></tr></tbody></table>

{% hint style="success" %}
**Recommended:** Leave the per-zone adjustments at their defaults unless you need to target a specific color zone — VIESUS already balances skin, sky, and vegetation automatically.

# 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.viesus.com/features/features/local-color-correction.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.
