flush

The term flush is often used in a poetic way to make mention of a reddish hue. Typically, the concept refers to Colour of the clouds when are they illuminated by the sun's rays.

The glow of the clouds may appear in the dawn and in the sunset. This feature, however, depends on the current weather conditions.

Reflection and refraction of the sun's rays are responsible for the glow. If the blush arises in the clouds, it is usual for observers to consider it an attractive spectacle to the sight and an inspiring phenomenon.

For example: "The glow of the sunset surprised us walking through the city aimlessly", "I woke up early with the intention of appreciating the sunrise, but it just started to rain", "The fire and the glow of the clouds combined to create a Dantesque scene".

The idea de arrebol is also used to name the coloration that cheeks acquire when someone is blush. The fact of blushing, meanwhile, is associated with feel ashamed: "After the romantic declaration of the young man, the girl began to notice a slight blush on her cheeks", "With his face flushed with redness, the boy got up and went to the front at the teacher's call", "A few red marks were soon drawn on his face.".

The dictionary of the Royal Spanish Academy (RAE), on the other hand, indicates that arrebol may refer to rouge: the cosmetic product used to modify the appearance of the cheeks by applying color.
