Vocaloid Hatsune Miku's hair color is commonly described as aquamarine. However, the color is debated among the fandom. It is described in other colors such as: aqua, teal, turquoise. It can be seen as green or blue, but KEI has drawn her to have a blue-greenish hair color on different occasions.

To put it simply, it is personal opinion if it is green or blue, or both. Some people will draw her hair noticeably green, others will draw her hair solid blue. Again, it does not matter, it depends on personal choice.
