“It was octarine, the colour of magic. It was alive and glowing and vibrant and it was the undisputed pigment of the imagination, because wherever it appeared it was a sign that mere matter was a servant of the powers of the magical mind. It was enchantment itself.
But Rincewind always thought it looked a sort of greenish-purple.”

From Terry Pratchett's 'The Colour of Magic".

I had a little project to create something using a quote about colour as a launching point. And so because the word Octarine spoke to me of the ocean, and of sea glass and coral and a bit of magic, I made 8 (because Oct) Octarine wands.
