Hai! I cannot say this is common in Indonesia and rest of the world. Just the page color of a newspaper.

In Indonesian, I think it can be possible to find "koran warna oranye" or "koran warna salmon terang".

"Financial Times" is an example. (at least at the moment)

From Wikipedia Indonesia: https://id.wikipedia.org/wiki/Financial_Times

And also, "koran oranye salmon". https://beritagar.id/artikel/berita/sampai-kapan-koran-oranye-ft-bertahan

koran oranye

Selamat belajar! :)

Well, I mean, if yellow journalism can exist, why not orange journalism?

i think it's just another silly sentence
