For some reason, white and gold things appear blue and black to a large number of people. As a demo for BattleHack LA, I built an app that automatically corrects the colors in your images in Dropbox so you can see their true white and gold nature.
The full code is on GitHub at github.com/dropbox/whitegold. The app uses webhooks and the Core API (
/files_put). It’s based heavily on the Markdown webhooks sample, so check that out too if you’re already sick of #teamwhitegold.
