And the lower a material's reflectance, the blacker it is.
However, you can pick and choose how you measure that reflectance and get different results.
And so we get the most light reflectance off those white flowers.
and so we get the most light reflectance off those white flowers, which will be ideal for nighttime because there's very low light.
Moreover, higher elevations accumulate ice and snow that increases Earth's albedo—the reflectance of solar energy.
