Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

tweakpane-plugin-wide-gamut

v0.2.3

Published

Wide-gamut colour picker for Tweakpane v4 — the native picker UI with an sRGB/P3 gamut boundary, across 11 colour spaces (HEX, RGB, CSS, HSL, HWB, OKLCH, OKLab, LCH, Lab, P3, Rec2020). No runtime dependencies — the colour maths is built in.

Readme

tweakpane-plugin-wide-gamut

npm CI Tweakpane v4 license

The expanded picker: an OKLCH colour area with the sRGB/P3 gamut boundary, a hue strip, and the OKLCH mode dropdown with L/C/H inputs

A wide-gamut colour picker for Tweakpane v4. It mirrors the native colour picker and adds an sRGB / P3 gamut boundary on the OKLCH L×C plane, plus 11 colour spaces to read and edit in. Live demo ↗

  • Drop-in — registered once, it claims any colour-string binding; no view parameter.
  • 11 spaces — HEX, RGB, CSS, HSL, HWB, OKLCH, OKLab, LCH, Lab, P3, Rec2020.
  • Wide-gamut — the sRGB/P3 boundary draws on the OKLCH plane; values keep their source format and support alpha.

Usage

npm install tweakpane-plugin-wide-gamut tweakpane
import {Pane} from 'tweakpane';
import * as WideGamutPlugin from 'tweakpane-plugin-wide-gamut';

const pane = new Pane();
pane.registerPlugin(WideGamutPlugin);

pane.addBinding({brand: 'oklch(0.7 0.15 250)'}, 'brand');

How it works

The colour maths — conversions across all 11 spaces, gamut testing, and gamut mapping — is written straight from the CSS Color 4 specification (and Björn Ottosson's OKLab), with no runtime colour-library dependency.
