If a person had no senses or emotion but could understand you logically how would you describe color?

Question

For instance, suppose you had a visit from Star Trek's Spock kind of family from another planet and they did not have emotion, sight, hearing, touch or smell but had had these things understandably described to them already except for color how would you describe color?

Any answer is a good answer so please give it a try.

Answer 1

I personally don't think it would be possible because there would be nothing to reference to.

Besides, if they didn't have senses and the like, how did they get here?

Answer 2

I think the answer you're waiting for is the definition of color in Physics. Colors are... a form of infrared rays... that have different wavelenths???:p Which, when not absorbed by a matter, bounces back and is percieved by the eyes as... that color:p But if these wavelengths are all absorbed by a particular matter, and no light bounces back, then it is percieved visually as "white". "Black" on the other hand is just the opposite, it is when all light rays bounce back.

I think you're a scientist so just define to us what colors are.

Answer 3

Colour is a visual perception that affects the way you think about certain things; for example, I don't understand stuff as well when when it is written in black ballpoint pen than in blue. Then again, this property of colour plays on your emotions, so if they're emotionless they probably wouldn't be able to understand.

Answer 4

absorbtion spectra of light wavelengths differ for many objects. Those objects whose light spectra appear in the ~400-800 nm wavelength bands appear by humans to have color. Depending on the wavelengths absorbed and reflected, different colors emerge.

Answer 5

WOW THAT REALLY TUFF...I DONY NO CAUSE EVERY COLOR COMES FROM ANOTHER
