Some materials like snow reflect almost all light, thus the albedo is close to 1 (meaning 100% of the light is reflected).<br /> <br /> White paper reflects most of the light, but it is not so bright as snow -- it reflects about 70% of the light and thus the albedo is 0.7.<br /> <br /> Some materials reflect very low light, such as black rubber. We still can see them, because our eyes are very well adapted to dynamic differences. Even when it reflects only a tenth of the light, it is still enough to see them well.<br /> <br /> Black rubber cable on white paper sheet<br /> Black rubber cable (albedo cca 0.1) on white paper sheet (albedo of 0.7).<br /> <br /> <br /> As a curiosity, this [https://www.youtube.com/watch?v=Iyt47egkTu0 scientifically created &quot;blackest&quot; material] reflects no light and thus has albedo of zero.</div>
