BEx Query Formatting

Dear Experts,

How can I add desired color to change the look and feel of any BEx Report. Also,

Is there any way to achieve this as in the screenshot. 
I wanted to show the result rows of a particular characteristic in green color instead of default  yellow color
in BEx Query while keeping the over all query result in default yellow color..

I was thinking about  using  Exceptions Alert Level : Green Color. I tried but not finding any way how to configure it

Would you please suggest ??

Many Thanks
