It's called "A Blue Object" because when light of many colors falls on it, it reflects the blue light toward your eyes and absorbs all the other colors, including yellow. So if yellow light is the only light falling on it, the light is all absorbed, none is reflected to your eyes, and the object appears black.
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
