Palettes for Tumblr

Features:
• Create your own palette, or choose from the built-in options
• Change the page font independently of your chosen palette
• Adjust the base font size

Usage:
Once you've installed the addon, click the addon icon in the browser toolbar to open its configuration.

This addon only affects pages updated to use Tumblr's new web interface. This means Tumblr pages that do not usually offer the "Change Palette" button will not be affected.
