What is 'objective' value?

[Excited Penguin]

I think the language we use when talking about value muddies up the waters, allowing for 'objective value' talks to slide in as a thing.  And I think it's because of the way we talk about subjective value as an abstract idea when the reality is it's no such thing.

What is subjective value really?  

It is a tangible biological process of evaluating the desires of an individual in a moment.  Really, it is only subjective in the sense that the scope only applies to one person in that moment.  But really, it is a fact.  A measurable truth, no different than eye color or gravity.  Person A at moment B values C.

So what is objective value.  Where does that exist?  How does it not contradict the truth that is the individuals tangible values?  

If I have blue eyes, Bob has green eyes, and Tim has yellow eyes.  The idea of a universal eye color is nonsense.  By describing things as tangible instead of opinions, it leaves no room for an overarching objective value to exist.

Am I missing anything here?

We need not concern ourselves with whether a value is objective or subjective, only with whether a value is conducive to the wellbeing of sentient creatures or not. If any one value is proven to not be conducive to wellbeing than it needs to be treated as that, namely bad. That's all there is to it.
