Highlights Gmail and Inbox rows on mouse over with nice and shiny colors.

Adds some colors to the letter rows in Gmail (including in multiple inboxes feature) and in Inbox. Also supports contacts list (https://contacts.google.com/).

Starting from version 1.1, you can customize the colors! :-)

Credits goes to stasnikiforov for the style format, and to Jhon for the idea (http://userstyles.org/styles/4725).
