Do paintings get darker over time?

Why do many glazes make a painting look darker?

Applying many glazes make paintings look darker because so much light is trapped inside the paint film. You can see that there are four light rays on this diagram to show the four ways that light can interact with the surface. Rembrandt is a master of indirect layering of color.

What would happen if the artist applied a dark opaque layer?

If the artist had applied a dark opaque layer instead of a transparent layer, the dark color would have absorbed all the light so the painting will look very flat. You can see that my light ray goes all the way through that layer to the ground.
