Without performing the experiment, we're prepared to go out on a limb here, and
wager our lives, our fortunes, and our sacred honor that it would remain red.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
blue
black
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.
A green object under green light would appear green, as the light matches the object's color. The green light illuminates the object, causing it to reflect the same wavelength of light that it absorbs, resulting in no change in its perceived color. If the light were a different color, the object's appearance would change based on the light's wavelength and the object's ability to reflect or absorb that light.
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.
A blue object appears blue because it absorbs most colors and reflects blue light. However, when a red light shines on a blue object, the blue object would absorb the red light and reflect blue, so it would still appear blue.
The red object would appear red under a red light because objects primarily reflect the color of light that is shining on them. Since red light contains mainly red wavelengths, the object would still reflect red light and appear red.
In blue light, a yellow object would appear dark or black because yellow absorbs blue light and reflects other colors. This means that the object wouldn't reflect any of the blue light, making it appear dark.
Strangely, it would become a brighter shade of yellow.
It would look like a very, very, very, very yellowy orange.
white shoes appear white because it reflects all 7 colours of white light when fallen on to it.Therefore if only yellow light is fallen on to this object it would give out light rays which are yellow in colour . so shoes would appear yellow.
