1) Red-Orange.
The brilliant embers of a true fire are impossible to mistake.
All other flames are corrupted forms of this ancient and pure flame.
2) Blue.
Cobalt flame, immensely hot.
Smoke from a flame this hot can reveal wayward spirits and bring light to the truth long lost.
3) Azure.
The light of the dead star Gnottis, like ever-shifting azure glass, chill to the touch.
The star is dim and still, a monument to what was, like a glass eye. Gnottis died before Neurim knew life, yet still it clings to life animated by the glass flame. It was carried to Neurim by the servants of the Bodyless Ones known as husks. The azure flame of Gnottis is said to bring life to the inanimate though harvesting the flame is nigh impossible.
4) Burgundy.
The light of love, passion, and death. Lit ever eternal in the Crematori.
In Sisthea the East the burgundy flame, carried from drowned Sisthea the West, burns eternal in the furnace of the great Crematori, where all Sistheans are burnt upon their death, their ashes feeding the flame. It is said that their passions color the flame. Such a deep and vibrant red could only be forged by love.
5) Magenta.
The light of illusion, a burning fire of falsehood.
It's a figment, really. An impossible sight born of an impossible color. All illusions are the shadows of this magenta flame. The most wily of illusionists can hide the flame, though novices and incompetents often fail to fool anyone with their magic. The flickering of a false flame gives it away.
6) Green.
Pale and sickly, simultaneously the color of half rotten olives and under-ripe limes.
Green flame roams the Eyeless Lands, brought by the ogres and their insipid illness from below. It is the flame of rot and disease, lit deep within the earth in the ancient city of Yersinia, long buried and left to rot and ruin. It is there that disease originates, and it is there that the sick flame burns brightest.
7) Royal Purple.
It is a regal flame, lit with a sense of self importance. It holds itself high.
It is the queen of flames, self appointed of course. Some believe it sapient. Grandiose arrogance allows fire to grow a mind. It thinks itself greater than you. It looks down at you with eyes made of drifting ash and tilts up a chin made of cinders.
8) Brass.
Liquid metal, flickering like fire.
A creation of the dwarves, once used by warriors who specialized in liquid metal weapons and armor. The art is mostly lost to the dwarves, stolen by the dragon-cult Hatavites.
9) Black.
It eats light.
An orcish invention, a flame designed to scorch gods. Few things can harm an idol and fewer still can harm divinity, but the horrid black flame of the orcs can. Enough flame and enough time will result in an undead god, the most powerful and twisted weapon of the orcs.
