IndexedImage Apply Palette

What is it for?

• Recoloring every pixel with the same index at once
• Changing only the color scheme while preserving pixel-art shading and regions
• Adjusting an extracted palette and applying it to the entire image

Overview

Replaces only the color table of an indexed image. Pixel indices—and therefore the artwork and shading structure—remain unchanged; only the colors referenced by those indices change. This makes the node a core building block for pixel-art color variants.

Usage tips

• The complete recoloring pattern combines the indexed_image from image_to_indexed_image with a processed palette from palette_adjust_hsv, palette_edit, or palette_set, then feeds both into this node. This lets you batch-produce multiple color schemes for the same artwork.
• Connect palette_cycle to create classic palette-cycling animation.
• Remember that palette order defines the indices. Any index without a corresponding palette color becomes transparent.

Related nodes

• image_to_indexed_image — upstream conversion to indices
• palette_adjust_hsv / palette_adjust_oklch / palette_set — process the replacement palette
• palette_cycle — animation use
• indexed_image_render — use when you want a temporary color-table override

How it works

• Every image pixel has an index such as 0, 1, or 2.
• This node preserves those indices and replaces only the colors they reference.
• For example, if index 0 is red and index 1 is black, supplying a palette where index 0 is blue and index 1 is white changes every red area to blue and every black area to white.

Notes

• Palette order defines the indices.
• An index missing from the input palette is rendered transparent.
• Transparent slots are normally handled separately from the palette array.

Examples

1. Connect indexed_image from Image To IndexedImage.
2. Connect the adjusted Palette to palette.
3. Review the recolored result from the image output.
4. If needed, pass indexed_image farther downstream.
