If you prefer very warm daytime colors, select Options> Expanded Daytime Settings from the f.lux menu.
Sunset is when the sun has set, but you are awake. If you are an early riser, this is also your pre-sunrise morning setting.
Sunset colors are designed to work well with normal warm white room lighting. If you usually wake up before sunrise, you might prefer a more moderate (4500K or brighter) Sunset setting.
