Change color of subject?

Is it possible to change the color of the sender, subject, and preview texts individually for read and unread messages in the inbox? I’m using the ‘Compact’ multiline view and changing the "MessagesMultilineFirstLineColor’ property seems to change both the sender and subject lines instead of just one. Also, the ‘MessagesUnreadForeground’ seems to change all the lines when I’d rather it just one. Is there an option I’m missing or is this the only option?
