Lorenzo,

Layers in Eeschema are only used in a few special cases.  Mainly to
determine if lines are defined as wires, buses, or graphic (not
connectable).  I'm not sure layers are really necessary in Eeschema.  I
would personally rather have separate SCH_WIRE and SCH_BUS objects
derived from SCH_LINE to handle the differences and do away with the
layers.  Given my current work load, this will be a discussion and a
project for another time.  So to answer your question, layers are a
legacy that need to be kept until they are replaced with an improved
design.  If I get some time, maybe I will take a look at ColorPin and
invert it to white or some other color when the background is changed to
black.
