The spider known as Adanson's house jumper has excellent colour vision, with three opsins (visual pigments), which makes them trichromatic, like us - but unlike us, the spiders have two opsins for visible light and one for UV. Dragonflies have as many as 30 opsins. But as the mantis shrimp demonstrates, more visual pigments doesn't necessarily mean seeing more colours.

Trinity

"The whole country was lighted by a searing light with the intensity many times that of the midday sun. It was golden, purple, violet, gray and blue. It lighted every peak, crevasse and ridge of the nearby mountain range with a clarity and beauty that cannot be described but must be seen to be imagined. It was that beauty the great poets dream about but describe most poorly and inadequately." — Brigadier General Thomas F. Farrell

"It was so brilliant purple, with all the radioactive glowing." — Frank Oppenheimer

"... there was an enormous ball of fire which grew and grew and it rolled as it grew; it went up into the air, in yellow flashes and into scarlet and green." — Isidor I. Rabi

(And Hiroshima: "The mushroom cloud itself was a spectacular sight, a bubbling mass of purple-gray smoke and you could see it has a red core in it and everything was burning inside..." — Staff Sergeant George Caron)

The Rainbow House of Chooka Frood

"Number 99 was an eviscerated ceramics plant. During the war a succession of blazing explosions had burst among the stock of thousands of chemical glazes, fused them, and splashed them into a wild rainbow reproduction of a lunar crater. Great splotches of magenta, violet, bice green, burnt umber, and chrome yellow were burned into the stone walls. Long streams of orange, crimson, and imperial purple had erupted through windows and doors to streak the streets and surrounding ruins with slashing brush strokes. This became the Rainbow House of Chooka Frood."

- Alfred Bester, The Demolished Man
