Palette Library

Five million palettes, and a 660-byte file.

The expanded collection was 3.9 GB, so it is not stored: every palette is computed from a seed as you scroll to it. That has a consequence worth knowing before you filter — nothing here can look at five million records, so a filtered browse says how far it actually got.

Filter by method, hue, chroma or lightness. A filter here does not narrow a list — it starts a scan, because five million palettes cannot be examined at once. The counter under the grid says how many were derived to find what you are looking at.
