DESIGN ELEMENTS OF WINDOWS LOGO
The Windows logo has traditionally
depicted a flag. Consisting of four
colored window panes or quadrants,
the
space between them made a cross, one
of the commonest elements in graphic
design. The quadrant and cross are
associated with earth and land. The
colors red, green, blue, white and
amber
strengthened the emblem’s association
with earth, through fire, water, flora and
fauna.
