Blue is a dark body, and can range from lighter gray to almost black, with a clear to muddy white shell, which is why there are many color variations within the range. Same with the jade, dark body in many shade variations, with a yellow shell ranging from the palest yellow to almost an orange. The thickness of a shell can also affect the appearance of the color.
