Post Color Highlight, needs redoing

[EmpireKicking]

This needs some more thinking put into it. I have some ideas to consider.

One: for each group, when you enable for the admin, you will see an colour box to pick what background and border colour, also having the transparent option for those that only want border. I added an CSS code to change around what I want, and one thing I noticed that it doesn't change the private message without added another line of CSS code for that.  

Plugin above seems to do the same thing yet it has more options for each group, The idea goes well with the default theme, colours does. Custom themes needs allot more tweeting in the CSS.
