What color on visible spectrum is the hottest?

Answer 1

According to human perception, the color with the highest value on the spectrum is white. The color with the most intensity (chroma) can vary from either red or yellow, depending. In the Science of human vision, we can distinguish between 7 different colors of the spectrum, but the spectrum actually contains an infinite amount of colors that human vision cannot process. Our eyes are createdto achieve 3 different (primary) colors that occur throughout nature. They are not red, blue, and yellow like so many people believe, but to be more specific they are Cyan (in relation to blue), Magneta (in relation to violet and red) and Primary Yellow (which as a pigment does not exist on this earth). From what the human perceives on the spectrum cannot be createdon pigment or paint (they are the purest and most intense colors in which humans cannot create with man-made materials). In pigment, the highest intensity would vary depending on the hue (color). Certaintints of red are more intense than yellow, but have a lower value (darker contrast). Yellow has a higher value (closer to white), but can appear less bright when adjacent to different colors than certain hues of red (example - Pyrrole Red is much brighter/intensethan Titanate Yellow, but darker in value (if you were to take a black and white photograph). The eye of the average human confuses brightness and intensity with warm colors, so therefore do not confuse brightness with "lightness".

Answer 2

Red. The frequency is highest at the violet and drops down as it comes down to red.

Answer 3

Infrared portion of the light spectrum is hottest which is colourless ie. Invisible.

Answer 4

purple (violet)

Answer 5

white

Answer 6

red

Answer 7

yellow

Answer 8

It would be Violet or Blue as they have the shortest wavelengths.
