Down by the Water

Blue is scattered more than other colours because it travels as shorter, smaller waves.
This is why we see a blue sky most of the time.

As the Sun sets, its light is passing through more of the atmosphere. Even more of the
blue light is scattered, allowing the reds and yellows to pass straight through to your eyes.

In photography, the golden hour is the first and last hour of sunlight during the day

In emergency medicine, the golden hour refers to a time period lasting from a few minutes to several hours following traumatic injury being sustained by a casualty, during which there is the highest likelihood that prompt medical treatment will prevent death.

Giotto di Bondone (1266/7 – January 8, 1337), better known simply as Giotto, was an Italian painter and architect from Florence. The Pope sent a messenger to Giotto, asking him to send a drawing to demonstrate his skill, Giotto drew, in red paint, a perfect circle, as though it was drawn using a compass, and told the messenger to give that to the Pope.

Reflections on still water are an example of specular reflection.

On Mars, the Sun appears only about two-thirds of the size that it appears in a sunset seen from Earth.
