I like that Luffy's main outfit colors (blue, red, yellow) are somewhat coincidentally based on the colors of the Philippine flag... Perhaps it is also a coincidence that his outfit turns white (the fourth "color" of the flag) in his Zoan (Awakened/Enlightened aka Nika) form and that his DF is the Sun God (sun is one of the symbols found in the flag)? Another coincidence would be the Wings being called the "stars" (which is another symbol) by Marco in a previous chapter... By the way, there are 3 stars and a sun in the Philippine flag...
