An object appears yellow because it reflects wavelengths of light in the yellow part of the visible spectrum and absorbs other wavelengths. Our eyes perceive this reflected light as the color yellow.
The yellow object will appear dark because it reflects yellow light, which is a combination of red and green light. Since only red light is being shone on it, the object will not reflect any light and will appear black.
Orange
An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
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.
A yellow object under a yellow light will appear very bright and vibrant, as the object will reflect the light in a consistent color. This can potentially make it difficult to differentiate between the object and the surrounding light source.

Red - Yellow light is a mixture of red and green light. When a magenta filter is placed in front of it, the filter would allow the red light through, but not the green, making it appear red through the filter. Anyone who listens to 'Anonymous' over me will see I am right when they pick up a set of filters.
it would appear orange
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.
It will look red. White light is made up of a spectrum of many colours. The primary colours are red, green and blue. An object (in white light) appears yellow because it reflects red and green light but absorbs blue light. In red light, the same object will simply reflect the red light. Since there is no green light, the object will appear red. (A mixture of red and green gives yellow)
A green object would appear darker and less vibrant in yellow light because yellow light does not contain much green light. This may result in the green object appearing more muted or closer in color to brown.
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.
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.
