This depends on what you are using the camera to find. If looking for a hairline crack in clay tile, then color would be the best choice. But if you are checking to see why a line is blocked, then black & white would be able to do the job. Black & white provides a crisper picture and lower lux (the amount of light required to obtain a picture) rating. However, color is best used for details, and identification when you need to know what exactly is in the pipe. For example, is the blockage grease, mud, or something else? Since technology has improved over the last couple of years, the price of color models has decreased dramatically. With color being more competitively priced, the majority of cameras now sold are color.
