Actually, I want to change the color of status bar text.
Usually, the color of status bar text is white. Such like: date and time, column and row.
But there is some another text which belongs to particular plug-gin.
For example, the git plug-in will output the branch name and some symbols on status bar.
I want to use different colors to let those text highlight. When you switch to different files, the highlight text will mention you strongly.
Your ideas are welcome here! 
Thanks.
