As such, the term Development here is used in the sense of Escher's own example, Development I, where lizards 'develop' from the outside to in of a chequerboard. Of course, one is not restricted to either this order (outside to in) or format (chequerboard), as other configurations are possible. Having discussed elsewhere the theory underlying Escher’s own developments: http://www.tess-elation.co.uk/how-escher-did-an-introduction/how-escher-did-development this section shows an arbitrary selection of linear and chequerboard examples and formats, shown in their finished state. Hand-in-hand with the process of development is the usage of appropriate colouring, which should be related to the outline in terms of intensity. The selection here was carefully chosen to enhance the intensity of the respective coloration, namely with blue and white for the linear strips (Nos.1-2). Furthermore, an additional linear strip is shown (No.3), whereby the complementary colours of blue and orange is desaturated back to a mid grey. The chequerboards (Nos.4-5) used complementary colours in juxtaposition (in this instance blue and orange).
The linear strip examples show an 8 x 6 format, with developments from extremities to centre (No.1) and from centre to extremities (No.2). As such, the colouration 'matches' the angularity of the lines, with a mid-blue chequerboard starting point followed by more intense colours as the composition develops.
Figure 1a: 8 x 6
A 'straightforward' development, with blue and white gaining in intensity from a pale blue chequer border at the extremities gaining in intensity towards the centre, in conjunction with the increasing degree of angularity of outline, from which the process then unwinds.
Figure 1b: 8 x 6
A 'straightforward' development, with blue and white gaining in intensity from a pale blue chequer border at the centre, gaining in intensity towards the extremities, in conjunction with the increasing degree of angularity of outline, from which the process then develops. Essentially, this is the inverse of No.1.
The chequerboard examples show an 8 x 8 format, with developments from extremities to centre (No.2a) and from centre to extremities (No.2b). As such, the complementary coloration of blue and orange matches the angularity of the lines, with a pale blue and orange chequerboard starting point followed by more intense colours as the composition develops.
Figure 2a: 8 x 8
Here the development gains in angularity of outline and colour intensity from outer to inner. Those familiar with Escher's Development I will see similarities here, in that this is fundamentally the same type of composition, albeit of different motifs, format and in coloration (with Escher's print being of lizard motifs, 10 x 10 and of black, grey and white) whilst retaining the same principles.
