In a standard game of Monopoly, what colour are the two cheapest properties?

In a standard game of Monopoly, the two cheapest properties are brown in color. These properties, known as Mediterranean Avenue and Baltic Avenue, are the first two properties players encounter as they start their journey around the board. The brown properties are situated in the lowest-rent district on the board and therefore have the lowest purchase price and rent values. While they may not initially be the most desirable or lucrative properties, they can still play a significant role in strategies, trade negotiations, and overall gameplay.
