Fast Image Color Analyzer: Average, Perceptual Dominant, K-Means, Luminance.

Extract key colors from images using optimized JavaScript algorithms.

• Average, Perceptual Dominant, and Top 5 Colors
• Uses K-Means clustering for precise palette analysis
• Highly optimized with Uint32Array and bitwise ops
• Perceptual analysis uses saturation + brightness weighting
• Processes 8 pixels at a time with minimal memory overhead
• Supports luminance-weighted color for realistic tones
