I think there should be a collaboration out there for every color that way it's easy for hitRECorders to find images/videos/poems/stories/anything involving the specific color they're looking for.

This is the collaboration for blue. It doesn't just have to be images.  If blue makes you feel a certain way, write about it!  In particular for blue, people could add blues music.  Or write about something that made them feel "blue".

This is a chance to be creative and stretch the concept of blue.
