Blue is the colour of the EU flag, together opviously with yellow.
They probably use green because it's easier to see. The human eye is more sensitive to green than it is to red and blue. Which is important if you want your customs officers to easily recognise the green bands. Apart from that, it's also the universal colour for 'safe', or 'no need to inspect'.
