Because it does and so do oranges. CHICKENS AND PIE!!! especially blueberry or cherry pie ! go and find out your self !!!!!!!!!!!! If it looked white, that would mean that all the components of the visible spectrum are being received by your eye. but in red light these colors are not around, except the red. So it looks red. The trouble is, that a white flag would also look red since a white object passes back any color you throw at it. So you wouldn't be able to tell if the flag IF SEEN IN DAYLIGHT would be red or white or any other color containing red. A blue object would look black.
