What is the meaning of this color scheme?

I noticed this magenta-black-green-red color scheme in the background of videos, and I am curious to what it represents. Maybe the black, green, and red are related to the Pan-African flag or the Palestinian flag? Either way, I think it is cool, I just wanted to know if it comes from something specific.
