Albedo is a measure of how much light that hits a surface is reflected without being absorbed. Darker surfaces absorb more light, thus decreasing albedo. Rougher surfaces can scatter light in various directions, but the color has a more significant impact on albedo, making darker surfaces the primary factor in reducing it.
