> Four in-house applets, each with its full state encoded in the URL so any view is a shareable link: OKHSL picker with, multi-stop gradient editor, lift a clean, and plot any palette.

Each tool keeps its full state in the URL, so any view is a shareable link.

- [Picker](https://colorcurio.us/tools/picker): OKHSL picker with gamut indicators — perceptually even lightness as you move across hues. State is encoded in the URL for easy sharing.
- [Gradient](https://colorcurio.us/tools/gradient): Multi-stop gradient editor with perceptual diagnostics and exports. Interpolates through OKLCh; exports as CSS or raw stops. State is shareable via URL.
- [Extract](https://colorcurio.us/tools/extract): Lift a clean colormap out of a legend strip, or extract dominant colors from any image. Runs entirely in the browser — nothing is uploaded.
- [Vectorscope](https://colorcurio.us/tools/vectorscope): Plot any palette or colormap on the OKLCh chroma/hue plane — a vectorscope that shows the perceptual footprint and hue coverage at a glance.
