We do.

Well, not necessarily from
everybody else, but between two individuals they may be perceiving the same color differently in their head. Assuming neither person has any observable difference detectable on an objective test (such as the
Ishihara Colorblind Test), there could still be differences in perception that we wouldn't be able to tell unless we were able to see from another person's brain/eyes. Perhaps one person's red-sensitive cone cells (in their eyes) are stronger than the other person's. They might see all colors shifted slightly to the red side of the visible spectrum (the first person might see a hue in-between yellow and green as more yellow, but would still call it yellow-green since their perception of yellow is actually slightly orange, if compared to the second person's point of view.)

I would sure hope not. I got quite a lucky leg-up in this "level" by being born in a developed country. All those babies out in the third world that die shortly after birth likely wouldn't be able to imagine the next level getting harder after that.
