Questions about Colour Picker

Does Colour Picker upload my files?

No. Colour Picker runs entirely on your Mac, so your files never leave it and it works offline.

Will Colour Picker change my original files?

No. Results are saved as new files in a dated folder in Downloads › OneMacTools, and your originals are left exactly as they were unless you turn on an option that says otherwise.

What does Colour Picker need?

Just a Mac with macOS 26 or later. There's nothing else to install.
