Who it suits
Cool undertones, fair or olive skin and dark eyes. If warm reds make you look flushed, a cool ruby may suit you better.
Ruby is a bright, cool red with a pink edge: the colour of a jewel rather than a flame. It is bold and very noticeable. See it on your own hair in seconds, before anyone opens a tube of dye.

A vivid cool red. On light brown hair it shows brightly with a little lift; on dark hair it needs lightening for full brightness.
Bright reds fade fastest. Cool water, a red colour conditioner and a gloss every 4–6 weeks keep it vivid.
Open the studio and add a portrait in even light with your hair in the frame, or use the demo.
Open More tools, then Hair, and pick Ruby from the vivid shades.
Set the intensity, drag the line between before and after, and save the card for your colourist.
Ruby is a cool, pink-leaning red; copper is warm and orange. Your undertone usually decides.
Expect noticeable fading in 4–6 weeks without top-ups.
Take it as a direction, not a promise. The salon result depends on your current colour, your hair’s condition, the products and your colourist, and the light in your photo changes how a shade reads.
The demo model is an AI-generated photo. Previews are made in the studio on your device and show a direction, not a guaranteed salon result.
