This question appears to be off-topic. The users who voted to close gave this specific reason:
Global colors is a custom palette you can use across all currently open sketch projects. If you have 3 sketch windows up with 3 different projects, you can use this palette across all of them.
The document-specific palette is just for the window/project you're currently viewing.
