Volcanoes appear brown and black due to the minerals and rocks that compose their structure.

Additionally, volcanic ash and tephra, which can be brown or black, contribute to the coloration. Weathering and erosion over time can also affect the appearance of volcanic rock, leading to varying shades in their surface.
