There is no API call to change or force users to use a certain Gmail theme. However, with the newly announced "Share your theme" capability, you could share your theme with users and require them to use that theme.

Question
I know how to enable and disable user theme choice in my domain management admin, but I'm hoping to do a custom theme company wide that is enforced inside Google Apps admin. Is this possible?
I've already put in a custom logo, but I'm hoping to just make a couple tweaks to selection, button and background colors.
