Green: Self-archiving of pre-prints* or post-prints** in repositories.
Gold: Publishing under a Creative Commons or similarly open license by a journal. Gold journals usually require authors (or another funder) to pay an article processing charge (APC) to publish.
Hybrid: A traditional subscription journal that allows authors (or another funder) to pay an APC to make their specific article OA. Differs from Gold in that a subscriber (such as a library) still needs to pay for access to the journal.
Diamond/Platinum: Journals that publish OA but do not require authors to pay APCs. These are usually funded by organizations or institutions.
Bronze: Free-to-read journals available on publisher pages. They usually lack an identifiable license.
*Pre-print: copy of the article before it has been reviewed by a publisher
**Post-print: copy of an article that has been reviewed and published, but not yet formatted for publication
