A hands-on comparison of how jet fuel, diesel, heating oil, kerosene, avgas and gasoline burn and what color they are. It shows that gasoline ignites more easily than jet fuel.

Neuroscientist Beau Lotto runs the audience through color and pattern illusions to show that perception is shaped by context and evolutionary history rather than being a direct readout of the world. The talk is playful and hands-on, and it argues that the brain interprets ambiguous signals.

Matt Parker explains the history behind NTSC television running at 29.97 frames per second rather than 30, tracing it to the backward-compatible addition of color. He walks through the arithmetic behind the odd ratio.

The trailer for Peter Jackson's They Shall Not Grow Old, a WWI documentary built from restored, colorized archival footage and BBC interviews with British soldiers.

Technology Connections experiments with filtering white and colored LEDs to make holiday lights look less garish. He explains why narrowband LED strings look harsh compared with incandescent bulbs.

The 8-Bit Guy explains the color limitations of 1980s computers and consoles such as the NES and Commodore 64. It shows how sprites, attributes and palettes shaped the look of old games.

A Climate Town episode on who uses America's water, particularly Western water. It looks at agriculture such as alfalfa and animal feed, and at water-rights rules that discourage conservation.

Vsauce explores qualia and whether different people experience colors the same way. It draws on color blindness, Mary's room, the explanatory gap and subjective experience.

Footage shot in New York City in 1911 by a Swedish film company, upscaled to 4K and 60 fps with neural networks and optionally colorized. The creator notes the colors are artificial and added only for ambiance.

A Technology Connections video weighing LED streetlights against high pressure sodium lamps, covering efficiency, color, cost and light pollution. It is a follow-up to his earlier explanation of why street lights are orange.

Denis Shiryaev's neural-network-upscaled, colorized 60 fps version of film footage shot in Paris between 1896 and 1900.

Kai Lentit's comedy sketch parodies a retro documentary interview with an Emacs enthusiast, joking about Emacs's endless configuration and devotion.

Technology Connections complains about the harsh, overly blue color of modern LED Christmas lights and tries more fixes for them. It follows earlier videos by the same creator on holiday lighting.

An Odd Lots podcast episode with Arizona hay farmer Trevor Bales on why growing alfalfa in the desert makes sense despite drought. He covers his family's history and the sun, pest and water arguments for farming there.

Stanford futurist Tony Seba argues that electric vehicles, battery storage, solar and autonomous vehicles form a 10x exponential disruption that will make fossil fuels obsolete within about a decade. It draws on his Clean Disruption book.

Mark Ferrari, the LucasArts background artist, explains in a GDC 2016 talk how he draws 8-bit graphics. He covers color cycling and palette shifting to create complex animated scenery without frame animation.

A short explainer on the history and mechanics of public key cryptography and the Diffie-Hellman key exchange. It uses a mixing-paint-colors analogy to show how two parties can agree on a shared secret in public.

Casey Muratori shows how fast a terminal renderer can run, building a simple reference renderer that handles Unicode and colored text far quicker than Windows Terminal. He argues that common excuses for slow terminals do not hold up.

Tom Scott-style absurdist tour by Tom7 of SIGBOVIK chess projects: a tournament of 30 weird chess algorithms used to rate a color- and piece-blind chess program. Topics include mirrors, arithmetic encoding, perverted game tree search and a diluted Stockfish.

The 8-Bit Guy covers IBM's 1981 CGA graphics system, including how composite output and artifacting produced extra colors beyond the nominal palette. He argues CGA looked better in period than it does on RGB monitors.
