Are "cosmetic" improvements possible in a console program without WinAPI?

Question

C++ / C#

Good time.
Situation: A small console program like " Hello world! ".
Written in C.
You need to make some changes to the console interface, such as changing the background of the console.
Question: is it possible to do this without using WinAPI ? Because The program is supposed to be cross-platform. I will also be very grateful if there is material (articles, books, videos) on writing console applications in pure C.
Thank you.

terminal
On linux it seems to work out of the box.
