I learned today about another 'colour' of open access journals: Platinum
'What is a platinum open access journal?
Platinum (also known as sponsored or diamond) open access journals allow immediate access to the content of the journal without the payment of a subscription fee or licence. Authors pay no article publication charge and all the costs of publishing the journal are met by one or more sponsoring organizations.'
Would it be true to say that all open access journals that allow immediate access to the content of the journal without the payment of a subscription fee or licence are 'platinum journals'? If so, then most OA journals are platinum.
