# Color Spaces and Settings

## Color Spaces

### HSV and HSP

The two primary color spaces in the plugin are **HSV** and **HSP**. The key difference is how brightness is calculated. You can see this most clearly in the Luma grid when switching between them.

### LOG and LOG2

`log` and `log2` modes are designed for lower-saturation images (for example flat or log camera formats). These modes apply a non-linear saturation transform. `log2` is stronger than `log`, so it is often better for very desaturated material.

In the Hue grid, this stretches color distribution from center outward:

Log spaces are also useful when you need more precision in low-saturation areas near the grid center.

## Macbeth Chart

You can open a Macbeth chart from the Options menu. It shows color chips with before/after values.

Hover over any chip to inspect RGB values.

This feature is available in the Pro version only.

## Settings

Open the settings window from the Options menu at the top of the viewer/window.

* **Custom UI scaling**: set a custom UI scale factor (useful on high-resolution displays)
* **White point snap**: enable magnetic snap for neutral points in Hue and Luma grids
* **Always reset points to original position**: when resetting points (context menu or `Alt + Click`), always return to original position and pin
* **Enhanced picker**: show before/after split view inside the color picker circle
* **Color picker area**: set the sampling window size (averaged result)
* **Color picker size**: set the picker circle size
* **Color picker format**: show values in `RGB` or `HSV`
* **Tone down saturation**: protect neutral colors from over-saturation
* **GPU mode for Window Mode**: choose processing backend for the dialog window
* **Force CPU render in Window Mode**: use CPU processing in Window Mode
* **Reload config file**: reload configuration from disk

## Color Picker

### Enhanced Color Picker

**Enhanced Color Picker** enables a split circle view:

* Left half: original color
* Right half: remapped color

### Color Picker Size

`Color picker size` controls the picker circle size:

### Color Picker Format

`Color picker format` supports:

* **RGB**: `0-255` per channel
* **HSV**: Hue `0-359`, Saturation `0-100`, Value/Lightness `0-100`

## Tone Down Saturation

**Tone Down Saturation** protects neutral colors.

When you move neutral points (the center point in Hue grid, and the central vertical line in Luma grids), saturation is applied with a lower factor to reduce clipping risk.

If you are correcting color cast or color temperature in neutral areas, keep this option enabled for finer control.

## Keyboard Shortcuts
