Cosmogone was a prime example, appearing orangey in photos but being more of a softer hue of nostalgia in real life. It was a color that had a sense of warm memory. Not the stark clarity of recollection created by violant, but instead a comforting idea of times gone by.
Apocyan was as far removed from cosmogone as violant was from irrigo. Cosmogone was soft and sedate while apocyan was sharp and aggressive. The color looked greenish-blue in recordings, but in reality it burned with the promise of the future. Not the warm thoughts of comfortable days, but the beating drive to an ambitious and unknown future.
It was a color that contrasted and complemented with peligin. Though it appeared black in recordings, peligin was much more complex. It was a deep color, one with near literal hidden depths. It was a color of unknown things, of dread in the dark or beyond understanding. A primal emotion bound to ink and paint by the arts of the Prismatic Laboratory.
Viric stood as its opposite. A color that looked bright green in recordings, it was a color that slipped from your mind, though not with the violent energy that caused irrigo to eject itself from a person's recollection. It was the color of willful ignorance, of ignoring a problem, or letting someone else worry about a situation. It contrasted with peligin's inevitable dread through a refusal to be acknowledged.
Then there was gant. Gant looked like an ugly shade of brown in photographs, but was much more than that. Actually, it would be more accurate to say it was much less. Gant was the color left by the absence of all of the above colors. That should have left nothing, but apparently there were worse things than nothing in this place. With normal colors combining all of them resulted in white light. With the Laboratory's pigments removing them left gant.
That fact alone was telling about the nature of these colors. They weren't obtrusions on reality so much as they were aspects of it, sent out of balance to the point where they became visible. If you remove them completely you don't get normal space. You get gant. A color of ends, not the dreaded end of peligin, but the inevitable cessation of all things. An end of self beyond which there will be nothing left. Nothing but gant.
