Logs can be colorized by installing Stylish, a browser extension for Chrome and Firefox that overrides CSS stylesheets, and writing a custom stylesheet.

Papertrail's log entries have various attributes that can be used to change css properties for specific programs or systems, or based on message contents.

Logs can also be colorized within the actual logs by adding ANSI escape codes (will override user-specific colorization).

The default view is mostly taken up by log events with a small row at the bottom for entering a search query, setting date range, accessing saved searches and enabling or disabling real-time logging.
