There are reasons why people all do not see the same, especially when it comes to colors.
Everyone sees the world from their own perspective, whether it be colors, shapes or people's characteristics.
But in the case of color, you are literally not seeing the color your brain is telling you.
Looking at the lemon above, it is clearly yellow.
In reality, there is not a pixel on the screen that is the color yellow. The computer manipulates what is seen by showing the exact same wavelength of red and green. If the color was orange, there would be a higher red wavelength than green to manipulate the brain into seeing orange.
