You also have to remember the scale rule when painting if you want realism . Colours fade with distance - hence the far mountains seem blue.
A 1/72 model at 1 yard will be +- the same shade as the real thing about 75 yards away. So the exact real colour does not look right - must be a shade lighter - but dont overdo it.
Don't use a gloss paint either - Satin varnish is more realistic even on a mahogany launch like a Riva or Chris Craft for instance
