Appearances can be deceiving.
1. Light is reflected, refracted and scattered at interfaces where there is a change in the refractive index. Mixtures containing different objects of the same size and shape and a similar refractive index are difficult to distinguish and appear homogeneous. One example id low sodium salt, which is a mixture of NaCl and KBr.
2. A mixture may appear homogeneous on a large length scale and yet be heterogeneous on a short length scale. This is an artifact of the limited resolving power of the eye with or without the assistance of an optical system. For example, pond water appears homogeneous to the naked eye, yet is teeming with microbes when viewed under a microscope.

Milk is one of these mixtures. It appears to be homogeneous because you cannot see different particles in the milk. It is actually heterogeneous because it is a colloid.
