COLORAMA

COLORAMA is a professional color palette extraction tool built for Unity. Whether you're building a stylized game, matching UI colors to concept art, or maintaining a consistent visual language across your project, COLORAMA gives you the tools to capture, organize and apply color palettes without ever leaving the Unity Editor.

Point it at any image — a texture, a camera render, or even your Scene View — and COLORAMA extracts the most visually meaningful colors using industry-standard quantization algorithms operating in perceptual CIE L*a*b* color space. The result is a native ColorPalette ScriptableObject asset.

Extraction

Three algorithms are available: Wu (Xiaolin Wu 1992, variance-minimizing histogram quantization — recommended), K-Means++ (precise cluster minimization in LAB space) and Median Cut (fast, great for quick results). All three operate in CIE L*a*b* perceptual color space, meaning distances between colors match what the human eye actually perceives.

Sources

- File — load any PNG, JPG, TGA, BMP, TIFF or GIF from disk (full resolution, bypasses Unity's import compression)
- Camera — render any scene Camera at custom resolution
- Scene View — snapshot the active Scene View camera instantly
- Batch — load a full folder of images and extract independent palettes for all of them in one click

Palette Editor

A dedicated Edit Palette window provides a full HSV color wheel with interactive drag, a brightness bar, harmony preview (Complementary, Analogous, Triadic, Split-Complementary, Square, Shades) with configurable angle offset, one-click add-to-palette for harmony suggestions.

Scene View Overlay

A persistent toolbar overlay displays the active palette's swatches directly in the Scene View.

Histories

Palettes are organized into named Histories (think folders). You can create, rename, duplicate and delete histories. Each history is a PaletteHistory ScriptableObject that holds references to any number of ColorPalette assets.

Remote Sync

COLORAMA can automatically pull ASE and ACO palettes from external sources on a configurable interval:

- Network Folder — any UNC path (\\NAS\share) or local absolute path
- HTTP/HTTPS — direct download URLs, one per line; Google Drive share links are converted automatically; Dropbox (?dl=1) and OneDrive download links supported
- Palette URL List — a ScriptableObject asset in your project listing multiple labeled URLs

Remote palettes are cached locally as ColorPalette assets and grouped into their own History. The sync state (last sync time, count, status) is visible directly in the Inspector.

Import / Export

- Export any palette to ASE (Adobe Swatch Exchange) or ACO (Adobe Color Swatches)
- Import ASE and ACO files (supports RGB, Grayscale, CMYK and LAB color spaces)
- Drag an existing ColorPalette asset into any History via the Inspector
