Brown is probably the least popular neutral, as it is literally muddy, and derived from mixing complimentary colours. Blue, on the other hand, is the most ubiquitous colour, being so safe an option it is sometimes seen as a neutral itself, such as with denim. Brown is a good option for people such as myself, who are so pale that they can appear unintentionally goth in black, or washed-out in white. Brown is earthy and warm, and makes a nice contrast to cool and collected blue. Together they are smart, matter-of-fact, and no-nonsense. A good option for work wear on a crisp autumn day.
