Klee is a measure of the amount of light reflected by something, while albedo is a measure of the amount of light that hits something.
The best way to think about it is that Klee is the ratio between the amount of incident light (the light that hits an object) and the amount of reflected light. Albedo is the ratio between the amount of incident light (the light that hits an object) and the total amount of light coming from that source.
Imagine you’re standing in a room with a single 100W bulb shining down on you. That’s 100W of power being unleashed on one point in space, so if we imagine that everything else in the room has zero reflectivity, then all 100W would hit you and there would be nothing left over for anything else to absorb or reflect – no matter how white or reflective your shirt was, none of that extra power would have any effect on it because all 100W would have been soaked up by your body instead.
Now let’s change things up slightly: instead of just having one 100W bulb shining down on us from above, let’s imagine we have 10 10W bulbs spread out evenly around us at different angles.
