The web store lacks tools for designers. Are there any good color pickers you’ve seen there?

I would disagree. It just lacks convenience app stores for mobile devices have. But no worries, I can recommend you a great color picker. Here’s the link for you https://chromewebstore.google.com/detail/quick-color-picker/mmjhombiehngfpipefodkebphfnblphe . Just click the link and see for yourself.

Maybe you are right. And thanks for pointing me in the right direction!
