ColorZilla vs Kernhue: which color picker extension should you use?
Short answer: choose Kernhue if you want a color picker, font finder and CSS inspector in one free extension, with OKLCH output and one-click export of a page’s colors as CSS variables, Tailwind or design-token JSON. Choose ColorZilla if you mainly need its CSS gradient generator, Photoshop-style color picker or multi-pixel sampling.

Where Kernhue is stronger
- One tool instead of three. Colors, fonts and CSS from the same hover — no switching between a color picker, a font finder and DevTools.
- Modern color spaces. Sites built with
oklch()and Display P3 colors are read correctly and can be copied as OKLCH. - From palette to code. The Tokens tab turns the page’s colors into ready-to-paste CSS variables, a Tailwind theme or W3C design-token JSON.
- Runs only when you click. Kernhue uses Chrome’s activeTab permission, so it reads only the tab you choose.
