Announcing Dye! (no relation)

Set a different theme color for each one of your apps: make Finder red, and Photos blue, each one’s tint’s now up to you.

Dye is a free, tiny app, handwritten with care. And it’s open-source!

@Cykelero I would never have thought that was possible 😲

@ff00aa It’s almost nothing: you just have to set the AppleAccentColor user default, for the app you want to tint.

But you have to first find the app’s bundle ID, figure out the ID of the color you want (graphite is not even a positive number), and manually quit and relaunch the app. So Dye really is a big layer of convenience, on top of a simple-but-cumbersome operation

@Cykelero Can you override any user default per-app? I could see it being fun to have some apps in high-contrast mode. Or even dark mode, though that's more of a dynamic setting so maybe it's handled differently
@ff00aa Oh good question. These might very well work, yes—theoretically you can set any default per-app, indeed, but some things do get read/imposed from other places in the system.
