## What is HueZoo?

Can you see the difference?

Huezoo is a color perception game that pushes your eyes to their limits. Six swatches appear on screen — one has a subtly different hue. 
Tap the outlier. Sounds simple. It isn't.

Difficulty is measured using ΔE (Delta E) — the scientific standard used by designers, display engineers, and color scientists to quantify how different two colors actually are. 
A ΔE below 1.0 is considered imperceptible to the human eye. 

Your goal? Find it anyway.
