Color of Berlin

A Twitter bot that tweets the color of the sky in Berlin.

This bot fetches the latest image of the sky in Berlin, crops and places it on an HTML5 Canvas, picks the color and matches it against a color list, fills a new Canvas with the color that was matched, then tweets the color name, image, and HEX value.
