Traces the 12-year self-archiving policy journey of the original 107 publishers listed on the SHERPA/RoMEO Publisher Policy Database in 2004, through to 2015. Maps the RoMEO colour codes (‘green’, ‘blue’, ‘yellow’ and ‘white’) and related restrictions and conditions over time. Finds that while the volume of publishers allowing some form of self-archiving (pre-print, post-print or both) has increased by 12% over the twelve years, the volume of restrictions around how, where, and when self-archiving may take place has increased 119%, 190% and 1000% respectively. A significant positive correlation was found between the increase in self-archiving restrictions and the introduction of Gold paid open access options. Suggests that by conveying only the version of a paper that authors may self-archive, the RoMEO colour codes do not address all the key elements of the Bethesda Definition of Open Access. Compares the number of RoMEO ‘green’ publishers over time with those meeting the definition for ‘redefined green’ (allowing embargo -free deposit of the post-print in an institutional repository). Finds that RoMEO ‘green’ increased by 8% and ‘redefined green’ decreased by 35% over the 12 years. Concludes that the RoMEO colour codes no longer convey a commitment to green open access as originally intended. Calls for open access advocates, funders, institutions and authors to redefine what ‘green’ means to better reflect a publisher’s commitment to self-archiving.
