What Is Duochrome Eyeliner? Duochrome vs Multichrome
What duochrome eyeliner is, why it shows two colours, how it differs from multichrome, metallic and holographic liner, and how to make the colour shift show.
By the VibeGlam team ·
Duochrome eyeliner is a liner that shows two different colours depending on the angle of the light. Look straight on and you might see cobalt blue; tilt your head and the same line flips to violet. Nothing changes in the liner itself. The colour you see depends on how light bounces off it.
Why does one liner show two colours?
Duochrome pigments are tiny, flat flakes coated with an extremely thin, see-through layer of mineral, often titanium dioxide. When light hits a flake, some of it reflects off the top of the coating and some off the bottom. The two reflections overlap and strengthen one colour while cancelling others. This is called thin-film interference, and it's the same effect that puts colours on a soap bubble or a film of oil on a puddle.
The colour depends on how far the light travels through the coating, and that changes with the angle. So as you move, the angle changes and the colour shifts from one shade to the other.
Duochrome vs multichrome vs metallic vs holographic
| Finish | What you see |
|---|---|
| Duochrome | Two distinct colours that swap as the angle changes, for example green to violet. |
| Multichrome | Three or more colours that roll through as you move, like the inside of a shell. |
| Metallic | One colour with a mirror-like shine. It catches the light but doesn't change colour. |
| Holographic | A rainbow spectrum, often over a silver base, that sparkles in all colours at once. |
| Shimmer | One colour with fine sparkle mixed in. Subtle, no colour change. |
Duochrome sits in the sweet spot: more movement than a metallic, but still clear enough to read as a colour rather than a rainbow.
How to make the colour shift really show
- Light matters most. Daylight, candlelight and moving light (think dance floor) show the flip best. Flat, overhead office light shows it least.
- Go a little bolder. A wider wing or a graphic line has more surface to catch the light than a hairline along the lashes.
- Layer it. Let the first coat dry for about 30 seconds and trace over it with a second coat for a stronger, more opaque shift.
- Try a dark base. A thin black line underneath makes interference colours look deeper and more vivid.
- Film it moving. A photo catches one colour. A short video of you turning your head shows both.
Ways to wear duochrome liner
- Everyday: a thin line close to the upper lashes. It reads as a colour from a distance and shifts up close.
- Night out: a sharp wing. Our winged eyeliner guide walks you through it.
- Pop of colour: a line under the outer third of the lower lashes, with black on top.
- As eyeshadow: dab a little on the lid and blend it quickly with a fingertip before it sets, for a shimmering, colour-shifting wash.
- Festival and graphic looks: floating crease lines, double wings and dots are where duochrome looks its most dramatic.
