After researching several sources I found that when you introduce a film you should have the same sound loudness level as you would want it to be throughout the film. When people turn on a film for home media consumption they will just the sound on there device within the first minute of playing. All this means that you should start away with the correct audio level from the start for the next minute or so.
"Audio is probably the most overlooked and under-appreciated aspect of the filmmaking process"
This means that in my thriller I need to start off with with some audio which will be at the correct level.
I also found out whilst researching that you should never go over 0db on the levels setting, this is because it will cause distortion, and will result in a poor audio quality. It you have ever heard a explosion scene on youtube you would have noticed that it sounds really distorted, this is because youtube uses a automatic levelling system, that can be overridden, that create a nasty effect. For safety reasons you should not have any peaks above -6db.
I found this chart online, and I found it useful.
Overall Mix Level: -10db to -14db
Dialogue: -12db to -15db
Music: -18db to -22db
Sound Effects: -10db to -20db with occasional spikes up to -8db.
Whilst there is not as much information available regarding the brightness, it follows a similar pattern, meaning that it is also fundamental not to start out on something that is too bight, or dark.
