This is a bit of a trick question! There isn't a specific name for this phenomenon.

Here's why:

* Light reflection: Darker objects absorb more light and reflect less. This is why they appear dark. Pale objects reflect more light, making them appear brighter.

* Contrast: The perceived brightness of an object is often influenced by its surroundings. A dark object placed on a light background might seem brighter than a pale object placed on a dark background, even though the pale object is reflecting more light overall.

So, while darker objects don't actually "show more light" than pale ones, they can appear brighter in certain situations due to the contrast effect.
