What is the color of the sky depending on the time?

I'm looking for a set of colors (HTML-Code), the sky has during sunrise, morning, forenoon, noon, afternoon, evening and sunset. A formula to calculate the color would be awesome.

    $\begingroup$ Even for a given time of day (and a fixed atmospheric turbidity), the color of the sky is different in different directions. Mitsuba uses the model of Hosek and Wilkie, which I assume is the state of the art. $\endgroup$

    $\begingroup$ When you say "sky" do you include clouds and the sun? Just earlier tonight part of the sky was bright pink and peach for a few minutes just before the sun went down. $\endgroup$ Nov 14, 2017 at 5:30

    $\begingroup$ You probably need the altitude, time of year, latitude, longitude, etc. to achieve a perfect result. For instance, there are days on the Arctic, when it's always black $\endgroup$
