The deep colour blue: often associated with vastness, the fear of the unknown yet calming, enduring and complete. Continuing from the last episode where we explored the colour Green, our three academic citizens help us explore and expand our understanding behind the symbolism of the colour blue. Our journey takes us from exploring the journey and unpredictability of the ocean with artist and oceanic researcher Meghan Judge, to understanding the noise pollution affecting our seas with zoologist and behavourial ecologist Professor Aliza le Roux and understanding how ocean can play a meaningful role in our food processes and health with artist and PhD candidate Zayaan Khaan.
