The colour-shifting garment, dubbed a chameleon shawl, was developed by Akira Wakita and colleagues at Keio University in Tokyo, Japan.
Interwoven into the scarf material are pixels containing red, blue and green light-emitting diodes (LEDs), so adjusting the brightness of each type of diode turns the scarf a different overall shade.
A small sensor embedded in the garment also enables it to identify the colour of the nearest item of clothing. A microcomputer then selects a suitable colour for the scarf itself to adopt…
(Fear not: very soon, those wily Japanese will find a way, as they do with everything, to fuck it.)
