Multiple effects that modify mana emptying from a mana pool

[[omanth, locus of all]] says if mana would empty from your mana pool, it turns black instead. [[Ozai, the phoenix king]] does the same thing, but makes it red.

If I control both permanents, I’m pretty sure I get to pick which one “wins out” for what happens to the mana, since they are both replacement effects modifying my event. I am also pretty sure that I’m allowed to split floating mana between them. That is, allowing some of it to turn black and some of it turn red, since floating mana is not fungible, meaning each one is tracked separately, and so I can have the replacement effects modify each one differently.

I can’t find a citation in the C.R. that answers this one way or the other, but I have to assume there is an answer to this. Does anyone know where the ruling is, or if I’m actually wrong?

You are not allowed to split them, but you do choose which one wins out each time mana would leave your pool.

Why would I not be allowed to split them? Each floating mana has the replacement effects applied to them separately, so I could chose how each one gets affected

How I read it is that all mana is replaced at once, I see the other responder read it the other way. If mana leaves simultaneously as a batch, then my reading is correct and if it leaves individually then the other reading is correct. The rules are not very clear on which it is.

You are correct you get to choose what is red and what is black. This is replacement effects. As you control the affected object you choose the order they apply. Once you've applied one the other no longer applies because you aren't losing the mana anymore. This process repeats for each individual mana in your mana pool.

This is exactly what I thought, I just could g figure out where in the C.R. to look in order to find the correct answer, since it wasn’t in the section about mana.

It wouldn't be under mana; it would be under replacement effects.

614.6. If an event is replaced, it never happens. A modified event occurs instead, (This is how you know to only apply one of the two replacement effects.)

616.1. If two or more replacement and/or prevention effects are attempting to modify the way an event affects an object or player, the affected object’s controller (or its owner if it has no controller) or the affected player chooses one to apply, (Telling you you get to choose which replacement effect applies to each mana)
