Introducing Satura: identify and understand color, online or off

Today we're releasing the first version of Satura, a free app for identifying, understanding and adjusting color - built for people with and without color vision deficiency (CVD). It runs right in your web browser, works offline once installed, and keeps everything on your device. There's no account, and nothing to download from an app store.

Identify any color

Point your camera at something, or upload a photo, and tap a point to get the nearest named color along with its HEX, RGB, HSL and LAB values. You can have the name spoken aloud, and switch between everyday color names, common crowd-sourced names, or a set of around 30,000 creative ones - whichever is most useful to you.

See how others see color

The simulator shows how an image or a live camera view looks with protanopia, deuteranopia or tritanopia, and a slider lets you dial the severity from mild to full. It's a quick way to understand what a friend, family member or customer with CVD actually experiences.

Check your own color vision

A quick, private Ishihara-style screening gives you an instant result, entirely on your device. It's a screening aid, not a medical diagnosis - but it's a useful first step.

Private and offline by design

Your camera feed never leaves your device, there are no tracking cookies, and once you install Satura to your home screen it keeps working with no internet connection at all.

This is just the start

Saved color libraries, correction filters, and everyday tools like match-or-clash and a contrast checker are on the way. Have feedback or a feature request? Email us at info@satura.app.
