Before suspecting your camera/lenses , you should understand why you see the color .
Color is the reflected light from the objects , the objects absorbed some parts of the spectum of the sunlight & reflected only a part of spectum so you only can seen the reflected part of spectum. So the same object will show its color slightly difference from different angles of sunlight ; another reason is the exposure value , same color with different exposure value will show different color , too . The photographing angle also will give different color due to polarised ( not adding PL) .
So many many factors affecting the color that you see (photographing) .
