Weather Models Colours And Reading?

[Deep Snow please]

I am currently in a bit of a state with models, I have only just started looking at them and need a few things cleared up so I can understand them a bit:

What is the difference between a 00zz and a12zz or 8zz chart?

Am I right in thinking that darker colours mean colder weather?

What do the different charts mean(sea level etc)?

Is using netweather the best place to find the charts(be honest)?

What is the difference between a 00zz and a12zz or 8zz chart? That's the time in which the model was processed and released 18z 6:pm ect

Am I right in thinking that darker colours mean colder weather? Darker purple colours indicate low pressure, the orangey colours indicate high pressure. The more orangey the colour the higher the pressure

What do the different charts mean(sea level etc)? We don't know, that's why the charts interpretate the data into 2M 10C M depth level...

Is using netweather the best place to find the charts(be honest)? Yes.
