As I previously said colours are only concepts, they never seem the  
same on two different occasions.  White light is the only natural  
light therefor the colors of objects illuminated by natural light  
will be perceived as those closest to the innate colour of the object.

As you said yourself, light light works as a catalyst for the colours  
of objects to be shown.  This can be extended to all types of light  
which we can 'see'.  If a room is dark there is an absense of light,  
there is no light to be shone on objects to illuminate them and show  
their colours.

Similarly, if a room is absolutely saturated with light everything  
will appear to have no colour and your eyes will have trouble  
focussing on objects.  This is because the light illuminates the  
objects to the degree where their natural colours are temporarily  
lost completely.

If an object is subjected to extreme lighting conditions for a long  
duration of time it will begin to permanently lose its colour.  This  
does not happen in darkness because colours do not apply to light;  
darkness is no more an excess of 'black' than light is an excess of  
'white'.
