This text proposes exploring the relationship between color, landscape, and architecture. It refers to the interrelation between the color of the landscape and architecture of one of the world's southernmost regions, Patagonia, at the southernmost tip of Chile. It is suggested that the chromatic atmosphere of this territory is marked by the vastness of the landscape, incorporating its architecture. The study is approached from an exploratory and chromatic observation perspective, through photographs and watercolors, supported by a historical and planimetric (plans and maps) literature review. The results show a complex territory, whose chromatic atmosphere evinces a deep and indissoluble link between color, landscape, and architectural heritage, concluding that the colors found onsite form an intrinsic part of this territory's identity.
