NORI_PIGMENT

There are many black foods in Japan, all of which have long been valued for their rich nutritional content. Nori, used for sushi and rice balls, is one such example. Do you know how the black color of NORI is produced? NORI PIGMENT is an experimental project by STUDIO BYCOLOR to explore the potential of pigments from the ocean.

Do you know how the black colour of NORI is produced?

For example, the paint’s red, blue and yellow pigments are all mixed together to produce black.
Similarly, it is known that the better the NORI is, the blacker it is and the higher the grade, as it contains many ingredients such as red, green and blue. There are phycoerythrin, chlorophyll, phycocyanin and carotenoid.

Through experiments to extract the colour, we have glimpsed that phycoerythrin plays an important role in photosynthesis in the ocean, where sunlight is difficult to reach , in the same way as in forests. In order to visualize the existence of the red colour behind the black laver, we created works using cotton, silk and wool as media, as well as Japanese paper making, which led to the creation of the laver sheet.

STUDIO BYCOLOR is a design studio that derives its appeal from colours and materials,
through this experimental project ‘NORI PIGMENT: Pigment from the Sea’, we will deconstruct the deep and beautiful black colour of seaweed and explore the attractiveness of seaweed itself from the aspect of pigment.

NORI PIGMENT:海からの色素

日本には黒い食べ物が多くありますが、どれも栄養が豊富なため古くから大切にされてきたものです。 寿司やおにぎりに使われる海苔もその一つです。

海苔の黒色が、どのように生み出されているかご存知でしょうか?
例えば、絵の具の赤・青・黄、すべての色素を混ぜ合わせると黒になります。
同じように紅藻素、葉緑素、藍藻素など、多くの色素を含む海苔は、良い海苔であればあるほど一層黒く、等級も高くなることが知られています。

太陽光の届きにくい海の中でも森林と同じように光合成を行うためには、「紅藻素」の存在が重要な役割を占めていることが垣間見えてきました。真っ黒な海苔から紅色の色素が抽出されるのです。海苔の裏側に在る紅色の存在を可視化するために、綿やシルク、ウールをはじめ、板海苔が生まれるきっかけとなった和紙などを媒体として用いた作品を制作しました。

STUDIO BYCOLORは、色や素材から魅力を導き出すデザインスタジオとして、この実験プロジェクト「NORI PIGMENT : 海からの色素」を通し、 海苔の深く美しい黒色を分解し、海苔そのものの魅力を色素の側面から探っていきます。
