Adjusts only selected palette indices together in OKLCH space.
Use it to darken all shadow colors slightly, increase chroma only in one gradient ramp, or gradually change specific colors through an animation input.
Overview
Adjusts selected palette slots together in OKLCH space. It applies natural, perceptual tone changes by slot, such as slightly darkening only the shadow ramp or muting the whole palette.
Usage tips
- This is the main tool for fine-tuning a color scheme. Select
alland adjust overall lightness and chroma to refine the tone without touching the artwork. - For a quick day/night variant, apply a darker, bluer adjusted palette to the same indexed image.
- The HSV version is more intuitive for dramatic hue rotations such as character color variants.

Index syntax
| Syntax | Meaning |
|---|---|
all |
Adjust every color |
0 |
Adjust only index 0 |
2,4,6 |
Adjust indices 2, 4, and 6 |
3-7 |
Adjust indices 3 through 7 |
Out-of-range entries in the text selector or Index List are ignored. In Auto or
Index Input mode, an out-of-range connected Index does not silently fall back to
text such as all: it leaves the palette unchanged and shows a warning near the
selection setting.
Index selection modes
| Mode | Description |
|---|---|
| Auto | Uses the Index List input when connected, otherwise the Index input, and finally the Index Spec text. If a connected input contains no valid index, nothing is adjusted. |
| Text | Uses only the Index Spec text; best for entering all or 3-7 manually |
| Index Input | Uses only the Int Index input; best for moving the target through one color at a time with time or an expression |
| Index List Input | Uses only the List Index List input; best for selecting multiple colors dynamically |
How to use
Connect a palette and enter the target color indices in Index Spec. For example,
enter 1,2,3 and set Lightness +/- to -8 to make only indices 1, 2, and 3
slightly darker.
Each adjustment can be promoted to an input pin. Drive it with Time Source or a waveform node to change palette colors over time.
To switch the target color during an animation, leave Index Selection Mode on Auto
and connect an Int to the Index input. As the Int changes through 0,1,2,3..., the
adjusted palette index changes in sequence. To control multiple colors at once,
connect a List to Index List.
