Rather than having to pick out your colors manually on screen, the patent imagines an Apple Pencil with photodetectors built in. That means you could point your new Apple Pencil at something in the real world – a shade of paint, say, or a flower – and instantly have the color available to doodle with on screen.

“The color sensor may have a plurality of photodetectors each of which measures light for a different respective color channel,” the patent reads. “The color sensor may also have one or more light-emitting devices. Control circuitry may use the light-emitting devices to illuminate an external object while using the photodetectors to measure reflected light to determine the color of the external object.”
While the patent is brand new – filed in November 2019, and only published on Thursday – we perhaps shouldn’t get too excited that a brand new Apple Pencil is just around the corner. Apple files a whole lot of patents – over 2,500 in the last year alone – and not all of them see the light of day. In fact, it’s worth reflecting on the fact that Apple filed a similar patent six years ago, and we still haven’t seen the tech utilized in any obvious way.
Still, the usefulness of being able to extract colors from the real world is pretty obvious, and it would be nice to see the Apple Pencil getting an upgrade. There are currently two generations, with the newer model being firmly “evolution” rather than “revolution”. It added wireless charging, a flat edge to stop it rolling away and some simple gesture commands. Both remain on sale, because each Pencil is compatible with a different set of iPads (opens in new tab).
Other innovations on the way for the iPad Pro include a Mini-LED display, which will supposedly offer all of the benefits of OLED without the threat of burn-in. You'd get the same great contrast ratio and truer black tones, as well as higher brightness. Mini-LEDs accomplish this by using smaller LEDs (light emitting diodes), as their name suggests, to power the backlights in displays.
In late June the iPad Pro with Mini LED display was reportedly entering trial production, which means it would launch at the end of this year at the earliest. But there's no telling whether this Apple Pencil breakthrough will be ready in time.
