Kikorangi blue is the colour of the densest ice and the highest sky. It’s a sparkling sapphire and the barrel of a wave. Blue is the fluke of a whale as it disappears into the deep and the plume of a tūī as it catches the light. Blue is the endless sky and the fathomless ocean joining Aotearoa and Antarctica. Kikorangi is the base of our flag, but is it the colour of our base? What is blue to you?
