After recovering from a moment of awe, I wonder why can't the photos be in color if it has full spectrum visible light sensors? From the description:

"Ralph consists of three panchromatic (black-and-white) and four color imagers inside its Multispectral Visible Imaging Camera (MVIC), as well as an infrared compositional mapping spectrometer called the Linear Etalon Imaging Spectral Array (LEISA)."

New Horizons team member John Spencer answered that question on the Unmanned Spaceflight forum:

Yes, this was a single channel image (we wouldn't have held out on you if we'd had color!). Several of our closest MVIC images were b/w rather than color, because of limited time near closest approach- we can take B/W images faster than color ones, and they allow higher-res LORRI riders. We still don't know what color the haze is, though we'll have lower-resolution high-phase color images soon, which will answer that question.
