Elementary is one of my favorite themes for Ubuntu. However in a recent update, panel has been changed to a darker color. I loved the light color and do not particularly like the new darker color.

If you are like me and want to change to a lighter color, you would be happy to know that it can be done very easily. Just follow these steps:

Save the file and close it.
Now logout and login again. You will get the light panel back.
