The color of an object depends on what wavelengths of light it reflects. If it reflects all wavelengths, it is white. If it reflects none it is black.
edit: my answer is white.
A mirror is not white, because white is a combination or mixture of all colours, not a reflection of all colours. A white shirt appears to be white because it scatters and so mixes all the wavelengths striking it. This explains why you can't see a reflection of the world on the shirt.
A mirror however doesn't mix all the wavelengths. Instead, the mirror reflects all wavelengths at the same angle that they strike the mirror, hence you can see a reflection of the world in the mirror.
Therefore, since the colour of an object doesn't depend on the wavelengths it reflects, but rather scatters or emits, then a mirror is exempt from a colour classification.
