POWERFUL TOOLS

Four ways to see color

HueScope packs four distinct color tools into one app — each designed for a different way you need to see the world.

Name any color
in plain English

Point your camera at anything and instantly know the color. Not just 'green' — HueScope tells you it's Fern, Sage, or Forest.

Up to 20fps identification — as fast as you can move

Accessible Names

been missing
