Light and time. A minute makes a difference, especially when it comes to the sun sinking into the horizon. 7:05 is pink and pale while 7:10 is orange and vibrant. Studying and capturing the millions of ways a sun can set and rise, they are like a snowflake; never to be exactly the same as before. Without the horizon to determine scale, the colors or the sky and the juxtaposition of the clouds can be digested and valued on a larger scale.
