There are five principal colors, namely,
white,
blue,
red,
green,
black...
For the number
five is better than all other numbers,
as
Aristotle says in the
book of Secrets..
Because the number
five distinguishes things
more definitely and better,
nature for this reason rather intends
that there shall be five colors.
Therefore these five colors are in
the
rainbow, rather than other colors,
in accordance with the
general arrangement of nature,
which carries into effect and purposes that which is better.

Wir können 5 Hauptfarben unterscheiden:
weisslich,
blau,
rötlich,
grün und
schwärzlich.
