When I first read The next evolution of labels I was not much impressed since I could see no immediate benefit with coloured labels. But I decided to give it a try and it improved readability and overview a lot.

I created some filters that put coloured labels on certain incoming mails. This makes it easy to see what’s in my inbox. In my case I set a dark green label on my RSS-feeds, label = !Feeds. This makes it very easy to spot the RSS-feeds, I only read them when I have enough time which usually is in the evenings. I also have filters and coloured labels for yoga-related emails and for some groups at Yahoo. Now I can easily pick the mails I want to read, depending on how much time I have at hand.

Note: The exclamation mark first in the label name places it on top in the labels list.
