FAQ
How is the palette computed?
The image is downsampled and bucketed by the top 4 bits of each RGB channel; the eight largest buckets return their weighted average colors.
Why do some colors differ slightly from what I see?
Bucket averaging merges close shades and dilutes extreme highlights/shadows — a tradeoff for harmonious palettes.
