Many sunrise pictures are oversaturated to increase the visual effect. There comes a time when we forget that nature is full of subtleties and that it is not always necessary to exagerate the saturation to obtain an interesting effect.
For this photo of a sunrise in Ogunquit, Maine, I chose to show the natural colors at 5h30 AM, in August 2019. There is no violet-blue nor citrus yellow in the scenery. Nonetheless, depending on your position in front of the screen, the colours will always vary somehow.
