Why is egg yolk oftenly termed as "pula" or red in the philippines?

I believe they are referring to the heart of the egg. Naturally when we think of a heart we immediately think it is red.

hmm actually for this, i asked my mom... :) she said the egg yolks before aare not what we see them as today. the yolk supposedly are very dark yellow - close to the reddish side, especially the native eggs. :D

I really don't know. I guess the posts above are the more logical explanations why the yolk is referred to as "red". I just came into this world knowing that this yolk is translated as "red" in tagalog and I didn't even bothered to think why that is.. lol.

I think it's because in the past Filipinos are only eating or using native egg yolks which are more orange in color which is closer to red. But now the white leg horn chickens which are layers known world wide are more productive in egg making produce faster but not as deep in color of the native kind, and so the native variety sort of vanished or not as abundant as it did back then. And because of that I conclude that they are just used to associating the egg yolk with "pula" just like certain brands for toothpaste, right? like "pabili nga po ng Colgate yung Hapee" hehehe.

Once upon a time (well, not too long ago), a lot of our Filipino folks get their eggs from native breed of chicken. These eggs have brownish shells and if you break and look at the yolk...it is actually dark orange in color, close to being red, hence they call it "pula".
