Color Adjust OKLCH

Adjusts a single color in OKLCH space.

OKLCH makes lightness, chroma, and hue easy to manipulate in a way that better matches human perception. Use it to extract one palette color and darken it slightly, reduce only a shadow color's chroma, or shift its hue a little.

Overview

Adjusts one Color in OKLCH (a perceptual color space). It handles delicate changes such as “make color 3 slightly darker and more muted” without unwanted hue shifts or unnatural changes in brightness.

Usage tips

• Use the standard three-node chain: palette_get → color_adjust_oklch → palette_set.
• The go-to pattern for shadow colors is to derive them from a base color by reducing lightness, adjusting chroma, and nudging the hue. The key advantage is that the shadow follows whenever the base color changes.
• For bold color swaps with large hue rotations, the HSV version is easier to predict.

Related nodes

• color_adjust_hsv — the counterpart for bold color swaps
• palette_get / palette_set — the go-to nodes before and after this one
• palette_adjust_oklch — adjusts multiple slots at once
• oklch_adjust — adjusts an entire image in OKLCH space

How to use

1. Use Palette Get to extract one color from a palette.
2. Make a small color adjustment with this node.
3. Use Palette Set to write the adjusted color back to the desired index in the original palette.

This lets you build per-color edits such as “make only palette color 3 slightly darker” as a node chain.
