idk why i built this. it's funny.
If you want more flags you will have to ~engage~ and write a comment for the algorithm. Who should we add next? You decide!

yep, based on luminance and individual color values (RGB). This allows the fire to follow patterns in the flag instead of burning everything at the same rate. I also tried it with a noise map so that pixels randomly have higher or lower resistance to the fire, but it was too random and didn't look right in my opinion.
I can tweak the values a bit though and the physics as well so they're just right. I was actually thinking of making red a bit more resistant.
Extremely satisfying, thank U ❤️
Unfortunately at present this seems to be causing some difficulty with black in the South Korea flag for vanquishing it completely.
I noticed as well, I'll try to deploy something so black is easier to destroy. probably just a bypass of the luminance system for very dark colors
okay all fixed, it was much simpler than that haha. burns nice patterns in the black pixels now :)
