Black Paper Smackdown: Which Black Paper Is the Darkest?
We compared four commonly available black papers: Plike Black, NT Rasha Shikkoku, OK AC Card Makuro, and Daiso Black Colored Drawing Paper. NT Rasha Shikkoku measured darkest at 3.35% average visible reflectance, against 6.02% for the Daiso paper. We also put it side by side with our own Fineshut SP.

The Blackest Permanent Marker: We Measured 8 Black Markers, Including Sharpie
We measured how much light eight black permanent markers absorb, from Sharpie to Japanese favorites like Magic Ink and Mackee. A matte paint marker won by a wide margin. Full results, why matte beats glossy, and how to get an even deeper black.
