The reason for the balck instead of the silver paint on the first photo is becuase you cannot paint a metallic paint over the radome. For some reason it affects the radar so most airlines paint it a different color than the base color if the paint is metallic.

According to the instructors in two different weather radar courses that I have attended, it had to do with the transmissivity (electronic transparency) of the radiomen. Up until the 1980's, the typical paints used on aircraft had very poor radar transmissivity. The paint which had the best properties for the radar just so happened to be black (or I think, gray). Now days, the paint manufacturers have improved their products to the point where it isn't a big factor anymore and you can paint radomes in just about any color.
