Laurent,

The question was aimed at Calvin but sent to the group so here is
my explaination:

1/ Longevity.

The green EL material lasts much longer than the other colors.

2/ Cost.

Green is cheaper.

3/ Luminosity.

The eye is most sensitive to green. For a given input power, green
appears brighter.

There are others but these are the main ones.

Regards,

PCBman
