The Barbie movie's use of pink paint created an international shortage of pink ... trends now

The Barbie movie set used so much pink that 'the world ran out of [it],' according to the highly-anticipated film's production designer. 

Director Greta Gerwig wanted to create 'authentic artificiality' for the Margot Robbie-led movie, so she requested everything to be hand-painted instead of using CGI, according to Architectural Digest.

As the visionary behind bringing Barbie's world to screens, Greta set her intentions early, telling the publication: 'Maintaining the "kid-ness" was paramount.

'I wanted the pinks to be very bright, and everything to be almost too much. [I didn't want to] forget what made me love Barbie when I was a little girl.'

She added: 'You have a painted sky in a soundstage, which is an illusion, but it's also really there. The painted backdrop is really there.'

The director believes that Barbie needs to be experienced using your senses, saying: 'Everything needed to be tactile, because toys are, above all, things you touch.'

Greta wanted Barbie's world to come to life physically, instead of just digitally, and to make it a fully immersive experience.

Getting the pink color 'right' was a huge mission and choosing the specific hue that would represent Barbie was a long process.

The iconic pink of Barbie's world was created thanks to Rosco's team of painters, who started with 100 hues of pink. 

After mixing the shades to create a perfect Barbie palette, they whittled it down to 10 pinks in total. 

The journey didn't only depend on the chosen color, but also how the paint would change hues when mixing with it with furniture or fabric.

Production designer Sarah Greenwood stated that reaching a conclusion was a consistent challenge.
