There are thousands of ways to build a
coloured world using Pi digits. For our
edition we supposed two main shades that
create a coloured region together with the
dark black shade. Two examples of possible
colour spaces are given below:
Color 1: Red
Color 2: Light Green


Color 1: Yellow
Color 2: Light Cyan


The Picture Book starts with a middle gray
shade for both main colours. Then  walking
along the Pi digits  the two main shades
slowly change, independently of each other
because they receive their respective colour
change information from 3 successive Pi digits each.
A certain shade taken from the coloured space is
then defined by the x/y coordinates in the coloured
space which are derived from 4 successive Pi digits.
Finally, this shade is used to paint the next square
on the Picture Book matrix.

Leafing through the books of this edition one can follow
the imperceptible colour change characteristics over
consecutive pages. You will find the complete colour evolution
at one glance in the Colour Index.
Each square in the Picture Book represents 10 successive Pi digits,
therefore one complete page consisting of 100 x 100 squares relates
to 100.000 digits. All in all the whole edition is a picturesque map
of a walk along 390.000.000 Pi digits.
