— feeling amazing
"“wizards, even failed wizards, have in addition to rods and cones in their eyeballs the tiny octagons that enable them to see into the far octarine, the basic colour of which all other colours are merely pale shadows impinging on normal four-dimensional space. It is said to be a sort of fluorescent greenish-yellow purple.”"
The Colour of Magic: Discworld 1 - Terry Pratchett, Nigel Planer

 

I love how he included rods and cones to make things legitimate and then added his own twist to it!
