Why does a red ball look black under a blue light?
The ball itself doesn't actually have a color. It simply has got the ability to reflect Red light, and we see it as having a red color. Light is buildt up by different wavelengts of light known as colors. All colors together form a warm white light. You can see the different colors of the sunlight if you use a prism. In any case, if you use only a blue light, Only the wavelength for blue, then the ball will appear Black because Blue does not have any Red in it. The Ball can not reflect red light if there is no red light to reflect :-)

Why are lights on radio towers sometimes white sometimes red sometimes blinking sometimes not and change from day to day?
Not 100% Certain, but based on my observations, I'd say it's either due to the type of structure it is, and how tall the structure is. There are those huge red and white towers that are used for airline communication during mid-flight. These always have Red lights the fade on and off. Antenna's (On towers or tall buildings) have white strobes Taller Bridges usually have constant red lights on the highest points. Again, these are only OBSERVATIONS!! : )
