At a glance, they enable us at once to
distinguish the noble from the ignoble, the prince from his subjects,
the master from his servant, and the widow clothed with sable weeds
from the bride adorned with her nuptial ornaments.
Since colours, then, are of so much value and importance, they may
be reckoned as holding a rank among the noblest natural gifts of the
Creator. As they are of such essential service to the inhabitants of
our globe, there can be no doubt that they serve similar or analogous
purposes throughout all the worlds in the universe. The colours
displayed in the solar beams are common to all the globes which
compose the planetary system, and must necessarily be reflected, in
all their diversified hues, from objects on their surfaces. The light
which radiates from the fixed stars displays a similar diversity of
colours. Some of the double stars are found to emit light of different
hues;--the larger star exhibiting light of a ruddy or orange hue,
and the smaller one a radiance which approaches to blue or green.
There is therefore reason to conclude, that the objects connected
with the planets which revolve round such stars--being occasionally
enlightened by suns of different hues--will display a more variegated
and splendid scenery of colouring than is ever beheld in the world on
which we dwell; and that one of the distinguishing characteristics of
different worlds, in regard to their embellishments, may consist in
the splendour and variety of colours with which the objects on their
surfaces are adorned. In the metaphorical description of the glories
of the New Jerusalem, recorded in the Book of Revelation, one of the
chief characteristics of that city is said to consist in the splendour
and diversity of hues with which it is adorned. It is represented
as “coming down from heaven, _prepared as a bride adorned for her
husband_,” and as reflecting all the beautiful and variegated colours
which the finest gems on earth can exhibit; evidently indicating, that
splendour and variety of colouring are some of the grandest features of
celestial scenery.
