What is the ESC sequence ESC + ]?

Question

Programming

The very essence of the question is stated in the title.
The fact is that I was looking for the ability to control the color of the cursor in the terminal, and I found the following code: At first I thought that these were the usual ANSI escape sequences that I knew well, but they begin with ESC + [ . Google did not give anything, so I ask the question, what kind of sequences are these? PS No, this is not a feature of printf, you can achieve the same with a regular echo.
printf "%d" "\e]12;green\a"
