The simple answer is black.
However, this is true only if the colour of said object is pure blue;
If it has even the slightest tinge of red in it, you will see a very dark shade of red.
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.
A purple colour will be formed
Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.
it will be black
White.
it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black
NO it is not true an OBJECT appears colour because it reflect that colour
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.

The colour an object appears to be is the colour of the light it is reflecting.

purple
BLACK
the black colour absorbs all the colour and reflects nothing.this is why it appears black in colour. :) lillyXOXO
