THAT ICE-BLUE SPACE:
I realised very recently that I had not told you the significance of the colour in the Ice-Blue Space.
This is it: There being no “space” as such the colour is only to signify or symbolize something to the viewer and, in this case, it is a feeling, a sense.
N.B. There is no space because space has dimensions – it is an Earthly construct*.
* From the OED/Lexicon
A Construct: An idea or theory containing various conceptual elements, typically one considered to be subjective and not based on empirical evidence.
