When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)
A green object would appear dark or almost black under yellow light. This is because yellow light consists of wavelengths that are primarily in the yellow part of the spectrum, and it does not contain much green light. Therefore, the green object would not reflect much light back to our eyes, resulting in its dark appearance.
When light is shined on a cyan object, it will appear cyan as long as the light source contains both blue and green wavelengths, which are the colors that make up cyan. If the light is white, the cyan object will reflect the blue and green light and thus still appear cyan. However, if the light is only red, the cyan object will appear black because it cannot reflect that color.
Black
When a blue light shines on a green object, the green object will absorb some of the blue light and reflect the remaining green light. This is because the green object absorbs light of complementary colors, in this case blue, and reflects light of its own color, green.
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.
The red light would be absorbed by the green object and the object would appear dark. The green object reflects green light and absorbs other colors.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
teal
When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.
A red object appears dark and almost black in green light because red objects absorb green light and do not reflect any light back to our eyes.
A green light makes a red object appear black, because red objects absorb green light and do not reflect any visible light back.
BLACK
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
black since the object is blue, it reflects only blue light thus, shining red and green lights on it will only cause the object to absorb the two colors and it will result to the appearance of the object as black
Red light shining on an object that reflects primarily red light will be red
