I learned from my Filipino GNIE classmates today that "green" for them is the same as "yellow" 黄色 for the Chinese when it comes to jokes, comics, dialogue, etc.
Then my classmates combined the 2 together and called their jokes yellow-green jokes. Then someone quipped, "Yellow plus green... equals purulent. Purulent jokes!"
We had a good laugh.

We were still joking about it during nursing lab today. Then another classmate chipped in that it's "blue" for the English. E.g. Blue movie (a film).
