Thank you to Gmail 2 highlighted rows - Default Theme by MrFreeze@userstyles and Gmail - Add Row Highlights by stasnikiforov@userstyles which this style borrows from!

This is a style that adds custom colors to the rows in your gmail inbox as follows:
1. Rows with unread messages have a light blue color
2. Rows get a brighter blue highlight as you mouse-over them
3. Selected rows have a light green color

The color choices work better with the light-colored themes provided by new gmail (in "settings"), but you can change them to whatever you want.
