What's the colour of magic?

“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.
