　The Colours are a strange form of sentient, vacuumdwelling pseudo-life which sometimes come to earth to breed.
Colours are completely non-biological and intangible -they are composed entirely of light and radiation. They come to Earth by "hitchhiking" on a passing meteor (or possibly a falling satellite or returning space probe).

　Colours begin life in their embryonic forms - small, calceous, hollow spheres about 3" in diameter. When deposited in a fertile place like a grassy plain or shallow body of water the embryo dissolves, releasing the second, or "larval" stage of the creature's life-cycle.

　The larva is a jelly-like substance that can grow to infest a wide area, almost like a fungal infestation. Wherever the lama spreads, vegetation begins to exhibit a prodigious but unhealthy growth. Fruit and vegetables become unpleasant tasting or inedible, and animals are horn deformed. All infected flora begins to glow at night with a color alien to the human spectrum (hence the name) and to writhe obscenely. In the advanced stages of the infestation, even local fauna (including humans) start to glow at night. Eventually, all the life in the infected area will die, and the area will no longer support plant life for an unknown length of time - at least decades, and perhaps centuries.

　Eventually, the larva transforms into the adult Colour, which takes the form of an amorphous patch of coruscating inhuman light. Although it is immaterial, the passage of a Colour can be felt - it leaves a sensation much like moving through a rather slimy vapor. Colours constantly emit radiation which can be detected by a Geiger counter. They can be clearly seen through light-intensification goggles, but do not register at all in the infrared. They are sometimes accompanied by a faint ozone smell. Without electronic detectors, it typically requires a Vision roll at 3 to detect the presence of a Colour.

　Colours live by feeding off the life-force of the surrounding area. As they feed their Wills grow stronger, and their attacks become more devastating. Each day the Colour can absorb enough life-force from the affected area to increase its Will by +l. It can also drain the life-force directly from a human being. This attack is insidious -the Colour simply surrounds the victim, and if the victim loses a Contest of Will against the creature he will permanently lose 1 point each from ST, DX, IQ and HT, as well as id hit points.

　People living in an area blighted by a Colour are also affected by the blight. Each day within the afflicted area (whether the Colour is in its larval or young adult form), the victim must make an unmodified Mythos Fright Check. Any appropriate mental disadvantages acquired from such Fright Checks will be of the sort calculated to keep the victim in the area - i.e., Paranoia (1 can't leave home - they're waiting for me out there), Compulsive Behavior: don't leave the area, Delusion: this is the best place to live, why would anyone want to leave?, Phobia, fear of strange places, etc.

　A Colour can focus its energies to dissolve virtually any form of solid material, but this is a rather slow process, and is ineffective as an attack. It's usually used to hollow out a lair for the Colour to hide in in the daytime. A Colour can disintegrate up to 6 hit points of inanimate matter per day.

　Finally a Colour can concentrate and form a solid seudopod which can grapple or strike. The pseudopod has 1d of ST for every 10 points of Will or fraction there of possessed by the Colour. This pseudopod can be disrupted and will vanish if it loses a Contest of ST by 5 or more, or by a single blow doing crushing damage equal to or greater than the pseudopod's ST.
Disrupting a pseudopod does no damage to the creature, however, other than preventing it from forming another pseudopod for at least an hour.

　At some point the Colour will decide it has absorbed enough energy, and will leave Earth to begin its life in interstellar space. This will not happen before the Colour has a Will of at least 30, and it might decide to stay on Earth a good deal longer.

　There is no known way to kill or harm a Colour. It is completely immune to physical damage (although the GM is free to rule that it is vulnerable to certain frequencies of light, radiation or even sound). Colours do, however, seem to be inhibited by daylight. They cannot attack while the sun is shining, and will usually spend the day in some dark, cool hideaway, preferably underwater. Wells, underground grottoes, sewers and the ocean depths are all suitable hideaways.
