When I was young, I spent a lot of my time before sleep wondering,
"Is the color I'm seeing as 'Red' is the color you are seeing as 'Red'? "
The meaning of Color
According to Wikipedia,
Color is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, green and others.
Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources.
Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells.
It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).
Basically, what wikipedia wanted to say is,
There is no color in the external world
No color! What does that mean? Now I have no idea how people make color pencils since colors don't really exist physically as it is, in a way. Since it derives from lights, well, I assume paint factory will need much lights to produce colors?
In fact, color is actually much more controlled by our brains than by our eyes. And that is confirmed by neuroscientists.
Perception
The keyword here ladies and gentlemen is Perception and it is safe to say that color is an illusion. What you perceive as blue may not be what I perceive as blue.
It's like this. We've been taught that an orange is orange in color. So when I see an orange, and when you see an orange, we both agree that the color that we are seeing is similar and is indeed orange. But you will never ever know if what I'm seeing as orange is actually what you are seeing as purple. So that's why it's a matter of perception.
Color Blind
So, some smart guys manage to figure that out with that theory and eventually came out with a test to tell if you are color blind or not. Color blind is the inability or decreased ability to see color or perceive color differences under normal lighting conditions.

Describing Color to Blind People
I spent a lot of my time before sleep wondering about this too, what do blind people see? That question is not even a valid question because blind people don't see!
Tommy Edison has been blind since birth. And he has a good sense of humor. His youtube channel is a blast. He produced online videos answering questions about life of a blind person. What a cool dude.
