Illusions of knowing the truth

Almost every people believe that they know the truth about at least one topic.
But how many of them know really?
we are never able to know the truth.
It sounds weird but I want to make an example to clarify that. We called the sun's color 'yellow', for everyone it is undoubted truth but there are some serious questions for instance what is yellow? do all yellow we saw the same? I mean there are color blind people. But science helps us to detect color blindness with the Ishihara test but this test is not all scientific and it is not the universal truth, Our eyes evoluted in the water to detect the sunlight, later to get information for hunting and surviving but imagine a sea animal build a civilization before us like almost humans. They have much better eye receptors because their eyes evoluted to see in the sea, so our yellow things would seem much different. So there is no yellow. If science doesn't develop like seeing the same thing with fish or something universally. But it seems impossible, imagine our cellphones have more pixels than we do we can't recognize so what is the point of that cellphone camera? It is the same thing with sea animals. I can extend my thoughts like what is real or is all a delusion ?but I don't have enough time and English to explain my opinions.
