3Blue1Brown is a math YouTube channel created by Grant Sanderson. The channel focuses on higher education mathematics with a distinct visual perspective. Some of the topics covered include linear algebra, calculus, neural networks, the Riemann hypothesis, Fourier transform, quaternions and topology.
The channel name and logo reference the color of Grant's right eye, which has blue-brown sectoral heterochromia. It also symbolizes the channel's visual approach to math.

Grant Sanderson is a math graduate from Stanford University. He worked for Khan Academy from 2015 to 2016, producing videos about multivariable calculus. After approximately one year, Sanderson quit to focus full time on 3Blue1Brown.
3Blue1Brown started as a personal programming project in early 2015. In the podcast Showmakers Sanderson has explained he wanted to practice his coding skills and decided to make a graphics library in Python, which eventually became the open source project "Manim" (short for mathematical animations). To have a goal for the project, he decided to create a video with the library and uploaded it to YouTube. On March 4, 2015, he uploaded his first video. Eventually, he started to publish more videos and improve the graphics tool.
Grant Sanderson animates with a self-made Python library, with the exception of some 3D animations where he has used macOS's Grapher application. The videos feature background music by Vincent Rubinetti, written specifically for the channel.
Since March 2015, the channel has over 70 videos uploaded, with mini-series on linear algebra, calculus, differential equations, and neural networks. The channel has collaborated with MinutePhysics to make videos on quantum physics and orbital motion. Two of the channel's videos have been featured on Popular Mechanics.
Sanderson has appeared on several educational youtuber's podcasts like the Numberphile Podcast, Siraj Raval and Showmakers, hosted by Sam from Wendover Productions and Brian from Real Engineering. Sanderson also briefly hosted is own podcast called "Ben, Ben and Blue" with Ben Stenhaug and youtuber Ben Eater.
