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:
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.
