Color, for everyone
Identify, understand, and adjust color - online or off.
Satura is an offline-first app for color identification and color-vision-deficiency accessibility - built for people with and without CVD. Your camera and photos never leave your device. No tracking, no cookies.
Features
Identify any color
Point your camera or tap an image to get the nearest named color plus HEX, RGB, HSL and LAB - spoken aloud if you want.
See through other eyes

Names you'll recognize
Choose everyday color names, common crowd-sourced names, or a set of 30,000 creative ones.
Screen your color vision
A quick Ishihara-style check with an instant result. Screening, not a diagnosis.
