Why do you call it a "white object" ? Could it be because it looks white under white light ...
light composed of every color ? Well then, the object must reflect every color.
So it appears to be the color of whatever light you illuminate it with. Yellow under
yellow light, etc.
An object that appears yellow under white light will have a tendency to maintain its distinctly yellow appearance when bathed in yellow light.
If the light is or contains the colour the object it is striking, then the object will appear to be the colour it originally is. If the light is not or does not contain the colour the object it is striking, then object will appear black. This is because an object will only reflect the light that is the same colour as it, all other light is absorbed. For example: Red, yellow, magenta, and white light will make a red object appear red as they all contain red light. Blue, green and cyan light will make a red object appear black.
It would look like a very, very, very, very yellowy orange.
it will be black
White.

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.
It will be green
violet, becasue of how the colours react to each other and how they work together to form green.
it will be black
White.
Red.
Our eyes only see the colours red, green and blue, in varying levels. It is our brain that converts combinations of these into the many millions of colours that we can perceive.An object that appears yellow under white light is reflecting colours that cause both our red and green cones (cells in our eyes that respond to colour) to fire. Note we have no yellow cones in our eyes.When the same object is placed under red light, then only red light is reflected from the object, and thus only the red cones respond, causing us to see the object as red.
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. :)
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.
