But even people who see colors might debate over whether it’s olive green or sage green. The green object actually has no inherent color in fact. How we see color is the effect of light hitting our retinas and our own visual apparatus.
Even if we can’t see, facts will always be facts and they will always be true no matter who looks at them, how we look at them, or our interpretation of them.
We've all seen examples of the difference between perception and fact when looking at some attractive selfies. If you take a closer look at the surroundings your opinion can change because of the facts of the sloppy background.
The fact is that the floor is littered with junk, clothes, shoes, and makeup. The perception, when the photo is cropped, is a neat-looking girl who has her act together. What is really the case, the facts, are what we need to rely on. Anything else can be manipulated or subject to errors depending too much on each individual and his or her interpretation of reality.
