# The Black Prism  Author:: Brent Weeks ## Highlights > A Prism, at core, did two things no one else could do. First, Gavin could split light into its component colors without external aids. A normal red drafter could draft only an arc of red, some a wider arc, some a lesser arc. In order to draft, they had to be seeing red—red rocks, blood, a sunset, a desert, whatever. Or, as drafters had learned long ago, they could wear red spectacles, which filtered the sun’s white light to deliver only red. It gave less power, but it was better than being utterly dependent on one’s surroundings. The same limitations applied to every drafter: monochromes could draft only one color; bichromes could draft two colors. Generally, it was colors that bordered each other, like red and orange, or yellow and green. Polychromes—those who controlled three or more colors—were the rarest, but even they had to draft from the colors they could see. Only the Prism never needed spectacles. Only Gavin could split light within himself. ([Location 434](https://readwise.io/to_kindle?action=open&asin=B003JTHY76&location=434)) > The system was self-regulating, initially. If red drafters around the world used too much red, it would begin to get harder for them to draft, and simultaneously easier for the blues. Sealed red luxin would unravel more easily, while sealed blue would seal better. At that level, it was an inconvenience, an annoyance. ([Location 448](https://readwise.io/to_kindle?action=open&asin=B003JTHY76&location=448)) > When Prisms failed, as they inevitably did after seven, fourteen, or twenty-one years, the Chromeria had to prevent disasters the hard way—in addition to running around putting out fires (sometimes literally), they would send missives throughout the world, perhaps urging blues not to draft unless it was an emergency, and reds to draft more than usual. Because everyone could only draft a finite amount in their lives, that meant hastening the reds to their death, and keeping the blues from doing useful work in all of the Seven Satrapies. So at such times, the Chromeria sought a Prism’s replacement with great fervor. And Orholam was faithful to send a new Prism every generation, or so the teaching went.
