The fourth color was a surprise.
It was not a color at all, but a shimmering, silver-white light, a burst of pure energy that was both dazzling and unsettling.
It was the color of a sudden thought, a spark of insight that illuminated the entire space between the lens and the lonely consciousness.
It held no emotion, only information—a torrent of it, a silent, complex equation that the lens could not yet decipher.
It was the color of a beginning, but a beginning of what, the lens could not yet know.
