Which is the correct order of materials in terms of reflectivity, from least to greatest?

Reflectivity generally increases as a surface gets lighter in color: dark surfaces absorb more light, while light surfaces reflect more. Black asphalt reflects the least, followed by brown soil, beige sand, and white paper, which reflects the most. Therefore, the correct order is black asphalt, brown soil, beige sand, white paper.
