Reference Color Extractor for Aseprite

Reference Color Extractor v2.0

Stop manually picking colors from references. Reference Color Extractor is a powerful Aseprite script designed to automate the process of creating professional palettes directly from your images. Whether you need the most dominant colors or a diverse representation of the entire image, this script provides the mathematical precision you need.

What's New in v2.0?

• Smart Sorting: Organize extracted colors by Hue, Luminance, or Saturation before applying them to your palette.
• Stepped Hue Algorithm: Improved hue sorting that groups dark and near-black colors together, preventing fragmented gradients and ensuring a more logical visual flow.
• Enhanced Append Mode: When adding colors to an existing palette, the script now automatically inserts a visual separator consisting of 4 black color slots for better workspace organization.
• Frequency Optimization: The dominant color selection has been refined to better filter out technical noise and duplicates, focusing on the most essential tones.

Core Features

• Three Advanced Extraction Methods:
  • Frequency: Extracts colors based on pixel count, ideal for capturing background tones and primary shapes.
  • Diversity (Median Cut): Ensures variety by capturing highlights, shadows, and small accent details that might otherwise be lost.
  • Balanced (K-Means): An iterative clustering algorithm that finds the mathematical "center" of color groups for the most natural, mood-accurate palette.
• Performance Optimized: Features dynamic downsampling to handle high-resolution reference images efficiently without freezing the Aseprite interface.

Flexible Integration:

• Replace: Completely replace your current palette with extracted colors.
• Append: Add new colors to the end of your existing palette, now with an automated 4-slot spacer for organized management.
