- [Narrator] Her eyes command a warm confidence,

her hair ripples as an ocean wave that laps provocatively

over her chest.

As the face of Starbucks since 2011 the siren logo

is alluring by design.

Beckoning you into the store to grab a latte or

a pastry.

Her face is so perfect it's its own mirror,

with the left and right sides copied to match up like

a Rorschach test.

She's beautiful and of course she's beautiful because

her face looks like its' a piece of perfect symmetry.

And we've long studied symmetry as the defining trait

of beauty.

But the secret you've probably never noticed about the

sire is that while her features look symmetrical,

they're actually asymmetrical.

Look at the right side of her nose and you'll see a shadow

that sort of dips a little bit lower.

I talked to Lippincott who actually developed this

logo for Starbucks in 2011 and it's a pretty

funny story.

Lippincott's job was to rethink this logo and they

decided, along with Starbucks, to break the siren out

and to make her the focal point.

When they were doing that they decided they had to

also make her more perfect.

If she was going to be zoomed in in her big close up

on the cover of packaging, on the front of stores,

they wanted her to be perfect.

So they slowly started refining her face to be perfect.

They made it a little bit skinnier,

a little more model like, and eventually they really did

succeed in making her perfect and they had her up

on the wall alongside many different iterations

and they couldn't figure out why her face just sort of

looked like a dead mask.

She didn't look friendly, she looked a little bit creepy.

She looked a little bit like a pseudo person.

What the designers realized was they'd made a mistake,

they'd made her too symmetrical.

So what they did was they went back to the drawing board,

they added a little bit more curve to the entire design,

but they really focused on the shadow of the face

and adding just a little bit of asymmetry.

Honestly it's just a few pixels in a logo,

but look at it and it makes all the difference

in the world.
