"An aspect of tessellation aside from the task of creating life-like motifs
is that of their subsequent coloration, of which this feature is the premise
of the examples below. Specifically, this refers to what I term as 'partition
coloration', in which the bird motif is divided into a series of regions (in
this instance, four - head, body, wings, and tail), and then coloured using
four colours (with the map colouring condition). The tessellation, of order
4 rotational symmetry, was especially chosen to complement this possibility.
The challenge then is to colour this in all possible distinct ways, of which
there are 5 examples, with 3 distinct types, as according to the vertex arrangements,
with colour distribution ratios of 1, 1, 1, 1 (No.1 and 2), 2, 1, 1 (No.3 and
4), and 2, 2 (No.5). The construction of this, along with other 'partition colorations',
is on my website. www.tess-elation.co.uk
