Screen Color Picker

About

A picker, nothing more.

Screen Color Picker is a one-tap screen color picker that runs entirely in your browser. No extensions. No native apps. No accounts. Just open the page and pick.

Why we built it

Every existing solution made us choose between bad options:

  • Browser extensions like ColorZilla need permission to read every page you visit, and most are ad-injected.
  • Native apps like Sip and ColorSnapper cost $10–25 and are Mac-only.
  • Online image pickers only work on images you upload — useless for sampling a color from your IDE or another desktop app.

In late 2021, Chrome shipped the window.EyeDropper API — browser-native, zero-permission, system-wide pixel sampling. Edge, Brave, and Opera followed. Most developers don't even know it exists.

Screen Color Picker is a clean, polished UI on top of that API. That's it. That's the product.

Our principles

  • 100% client-side. No server processes your colors. No telemetry. No remote dependencies at runtime.
  • Zero permissions. Screen Color Picker can't read any of your other tabs, even if it wanted to.
  • Free forever. No accounts, no Pro tier, no usage caps, no ads.
  • Web-native. No app to install, no extension to add. Just a URL.
  • Open source. Code is on GitHub, MIT licensed. You can self-host or audit it.

Tech stack

  • Astro 6 + Tailwind v4 — static site, minimal JS, zero runtime overhead
  • Geist + Geist Mono via Google Fonts
  • The native window.EyeDropper API — no canvas hacks, no library
  • The getDisplayMedia API for screenshot fallback in Firefox/Safari
  • localStorage for palette history — never leaves your device
  • Custom sRGB → OKLab → OKLCH math (no color-conversion library needed)
  • Deployed on Cloudflare Pages — free, fast, global CDN

Who's behind it

Built by Shrestha Tripathi, an indie developer based in India who got tired of installing browser extensions for tiny utilities. Part of a portfolio of worksoffline.in tools — software that runs entirely on your device, with no server, no signup, no data leaving your machine.

100% free, forever

We will never charge for Screen Color Picker. There are no plans for a "Pro" tier. No ads. No tracking pixels. No "freemium upsells." If we ever break this promise, you have permission to publicly shame us.
