Time of day best suitable for filming

When filming my trailer it is important that I film it at a suitable time of day so I get a good picture quality and it contributes he horror genre. The most suitable time to film is around 4:30pm because this is the time where it begins to get dark but it isn't too dark to see. This is the best time because it means that the footage will come out quite dull making it relate to the horror genre; however it isn't too dark so this means that you can still see clearly what is happening. The last thing I want is to film good footage but it turns out you can’t see what is happening because there isn't enough light.
