Dropbox Demo Fixes the Dress’s True Colors

In a nod to the viral debate over whether a certain garment is blue and black or white and gold, Dropbox developer Steve Marx built a demo app for BattleHack LA that automatically color-corrects images stored in Dropbox. The tool is designed to reveal what Marx calls their "true white and gold nature," countering the perceptual shift that makes many viewers see the dress differently.

The app relies on Dropbox webhooks and the Core API, specifically the /delta, /thumbnails, and /files_put endpoints. It draws heavily on Dropbox’s existing Markdown webhooks sample, which Marx suggests as a reference for developers already tired of the dress debate. The complete source code is available on GitHub at github.com/dropbox/whitegold.
