I've used the same tiny app called Couleurs for years. Click the icon in my menu bar, grab a color off my screen, get the hex code, paste it wherever I need it. Small thing, but I do it constantly — dozens of times a week, honestly.
A while back my Mac popped up a warning: this app was built for old Macs and won't be able to open much longer. The person who made it stopped updating it years ago, so there was never going to be a fix coming.
I didn't want to go shopping for a replacement and relearn a new workflow for something this small. I liked exactly how it worked — I just needed it to keep working. So instead of looking for another app, I built my own version.
It does the same thing Couleurs did for me: lives quietly in the menu bar, one click opens a little magnifying tool to grab any color on your screen, and it copies the code straight to your clipboard so you can paste it right away. It also keeps a strip of your most recent colors so you can grab one again without re-sampling it, and the little window stays put on your screen while you work instead of disappearing the second you click somewhere else — handy if you're bouncing between an app and your color picker a lot.
If you've ever had a little app you depend on just stop getting updates on you, you know the feeling. Figured I'd share mine in case it's useful to you too.
It's free to download (or pay what you want, if you feel like it): bereto.gumroad.com/l/colores
