Serious version: Dusk and dawn are similar to a certain extent, with hazy light and shadow and gray-blue tones. However, the dark colors of dusk will become heavier and heavier until they are submerged in darkness, while the bright colors of dawn will become brighter and brighter until the sun shines. This is the biggest difference between the two, but it is not easy to distinguish this difference.
In a sentence: The girl holds the lamb and runs towards the dawn.
