I admit, my first thought on seeing the title was "What's wrong with xxd?" This is nice! I like the colorization a lot -- it's like with source code, you don't realize how much you rely on the colors until you get a new computer and need to download syntax definitions for your editor again. Only feature I really think is missing is line numbers. Nicely done!

Sharkdp is also responsible for some fantastic tools like hyperfine for micro benchmarking, fd for finding files, bat which is a colorized cat replacement and many more such utilities. https://github.com/sharkdp is a real treasure trove of user-friendly CLI tools.
