What if red ran out

The other night while eating dinner, my mother aksed, "What if red ran out?" Natrally, she explained why she asked before we could even answer. It ends up that it's the title of a poetry book by Katia Grubisic.

Personally, I wonder what it means by 'what if red ran out', but it's a poery book, so you can't really expect it to make too much sense. But it got me thinking nonetheless. What's red?

Apples.
Blood.
Wine.
Strawberries.
Rasberries.
Love.

What if all of that just vanished? We would die, of course. People can't live without blood! And red means blood, and without red, we are without blood.

So if red ran out, we would all die. TA-DA!
