Colour,
verified.
Cora measures colour the way people see it, so online clothing sellers can describe a garment accurately and buyers can trust what they see.

Your photo. Your garment.
Tap the fabric and Cora tells you the true colour, then recolours the photo to match it.
Try it on your own photoThe colour problem costs everyone
Photography lies
Camera sensors, lighting and white balance distort colours. You describe "navy" and the buyer sees "black".
Screens vary
Every device displays colours differently. That "true red" on your screen is "orange-red" on theirs.
Returns kill margins
Colour mismatch is one of the most common reasons for a "not as described" return, and every one of them costs you the postage twice.
How Cora works
Four steps to a colour you can stand behind
Capture
Photograph your garment with any phone. No special equipment needed.
Extract
Cora reads the garment colour from the photo using perceptual colour science, on your phone.
Verify
Match the on-screen swatch to the garment in your hand. You confirm what is true.
Save
Keep the verified colour name and the recoloured photo. Sign in to keep them on all your devices.
Built for accuracy, designed for ease
Everything you need to describe colour with confidence
Perceptual Colour Science
Uses CIEDE2000, the colour-difference formula the paint and textile industries rely on.
Human Verification Loop
You confirm the match. Science bounds the options, but you verify the truth.
600 Named Colours
A palette of 600 named colours, drawn from a pool of 3,435 and curated for clothing. "Dusty Rose" and "Sage", not generic hex codes.
Photo Colour Correction
Cora recolours the garment in your photo to the verified colour. Calibration, not filters.
Named, not guessed
Every reading lands on one of 600 named colours, so "Dusty Rose" means the same thing to you and to the buyer.
Fast and simple
Photograph, tap, done. No setup and nothing to learn.
Colour science, made simple
Cora uses the same colour measurement standards trusted by professional industries worldwide.
