The fact that we may technically perceive things differently doesn't matter.
If the blue I see is not the blue you see, it doesn't change the fact that we both agree that other things we see like that are also perceived as blue.
When this isn't true, that's when we discover certain things about our biology. Color-blindness, for example.
So the question of what are things like "independent of any human perception" is kind of a non-starter. They are almost always exactly like they are when being perceived. A tree falling in the forest does everything necessary to create sound. Whether it makes a sound or not depends on how you define sound. If you define it as the various vibrations in the air, then you could say it does. If you define it specifically as those vibrations being received by something capable of interpreting those vibrations, then it doesn't.
The only counterexample is the double slit experiment. However, at that level, our observation is no longer technically passive. So it is possible that our observation is the element that changes the behaviour of the particles.

However, that simply shifts the problem. The number you see on that machine could differ from the number you saw yesterday because of the same faulty visual perception. I find this kind of uncertainty to be a real challenge with emotions. Am I judging someone more leniently than I was yesterday become of my emotions? Can I even judge my emotions properly in state of happiness?
- bena 4y agoIf the universe is changing in that manner, so? It doesn't matter. We can only deal with the world as it presents itself currently. You're dipping a bit into solipsism. "We can't be sure of anything external to ourselves." I love to slap people like that and then deny it until they can prove that it happened, using all of the solipsistic arguments to dismiss their claims. You'll find people are really ready to dismiss solipsism in the face of being slapped in the face. You are the only true judge of your emotions. If you think you're feeling something, you're feeling it. And yes, your emotions will color your actions. But that's irrelevant to whether or not something is blue.
