Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
Believe it or not, the object will appear black! Here's why. An object is red because it absorbs all wavelengths of light except red. It reflects the red back to our eyes, so that's what color we perceive. If you, then, have no other light source and shine purely blue light on a red object, the object will absorb the blue light and you won't get any light reflected at all. In other words, black.
The light spectrum is composed of multiple wave lengths. Different objects will either absorb or reflect particular wavelengths of light. Humans can actually only perceive 3 different categories of light, red, green, and blue.When you perceive white paper, you are perceiving all 3 components of visible light, red, green, and blue. The bleaching and the construction of white paper is thus made to remove the components that absorb light, and leave the components that reflect light. There is an element of glossiness which is the ability to reflect light directly, and flatness which would be the ability to scatter light when reflecting, giving a white finish rather than a mirrored finish.If you look at red paper, then the green and blue wavelengths of light are absorbed by the paper, and the red wavelength is being reflected back.If you look at green paper, then the red and blue wavelengths of light are being absorbed, and the green is being reflected back.If you look at blue paper, then the red and green wavelengths of light are being absorbed, and the blue wavelength is being reflected back.Black paper will absorb essentially all of the light.Different colors will reflect and absorb the three basic components of light in varying amounts.
When you mix the three primary colors (red, blue, green) you get white..................................................................................................................YOU CAN'T GET WHITE!! YOU WILL GET SOMETHING DARK KINDA LIKE DARK BLUE CLOSE TO BLACK!! YOU SHOULD TRY IT IF U GET WHITE I WILL GIVE YOU $1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
Objects appear in color because they reflect that color. Tree leaves appear green brcause they reflect green (and transmit green) so you know they don't need green light to grow. White lights contains all colors. A white object reflects most of them. A black object reflects very little light, so it appears black. Obviously with all that energy being absorbed, the temperature must rise, and that is true.
No black paper is not translucent ts opaque
will appear black
A ripe banana will appear black when illuminated with red, green, or blue light, as these colors are absorbed by the banana's pigment. Only yellow light will be reflected, making the banana appear black under the other colors of light.
A white car would appear black under blue light, as the pigments in the white paint do not reflect blue light and therefore absorb it, creating the appearance of black.
A green object will appear black if only blue light is shone on it because blue light is absorbed by the object and green is the complementary color of blue.
Any black thing, including soya sauce, will appear black because it absorbs most of the light that falls on it. So why do "black things" absorb light? Because their surface or their interior is unable to reflect light. (In other words, "because it does". Why do metals appear shiny and metallic? Because they do!) Black things will normally appear black in other light; but other colours may appear black in other lights. For instance, a blue object may appear black in orange light, because orange light has little blue within it for the "blue" object to reflect.
A red ball would appear black in blue light because red objects absorb blue light and reflect little to no light of that wavelength. This causes the red object to not reflect any light back to our eyes, leading us to perceive it as black in blue light.
The green object will appear black because it will not reflect any of the blue light shone on it. Green objects primarily absorb blue light, so without any green or red light present, the object will appear dark.
Black
A cyan stage light would make the red shirt appear black because cyan is the complementary color of red. A yellow stage light would make the blue pants appear black because yellow is the complementary color of blue.
An object that appears blue in white light does so because it absorbs all colors except blue, reflecting blue light. However, in green light, which does not contain any blue light, the object cannot reflect blue light and would therefore appear grey or black as it does not have any other color to reflect in the green light.
