How are we enabled to see the black colour?
How we could see black colour which has no wavelength?
Is black really a colour? Why in black body light green colour is not visible? What is a black light? Is a UV light the same as a black light? Is black a color? Is there a color darker than black? Can a light change its colour if its wavelength changes? Why is the absence of light black? If black is not a color, what is it? How do photons have colors? Why does black colour absorb heat? Why no real source of light can ever be truly monochromatic? What is the wavelength of monochromatic light? During sunrise and sunset, if all of the visible spectrum except red has been scattered away, why does a green colored object not appear black? Is black not a color? If people were able to see a broader spectrum of light, would we perceive more colors? Is neon black a color? Is black or white the absence of color? Why is it that sometimes I can see in the dark but other times it is pitch black and I cannot see anything? How could science determine if there was a type of light outside of the spectrum visible to us or our current technology? Why are people in hot climates generally dark skinned, despite black absorbing light? How many colors can humans see? How do photons create color? Is it possible to "see" color in black and white pictures? Can human eyes be modified to make us see/sense wavelengths beyond the visible spectrum? Why are rain-bearing clouds usually dark in colour? What's darker than black? Why do ultraviolet lights have radiation? How does color of light changes in the given scenario? What is the wavelength of mercury light?
