Art people do some wonderful creative spelling.
There are times when the correct way is "officially" best but there
are some cultural differences too.
Colour in OZ as opposed to color in the US.
I know many artist for whom spelling is not a naturally easy activity
and others for whom it is essential.. It may have to
do with the visual recognition of a word!
Then there is the "Craft" aspect of accuracy.
Anyway we all knew what the variations on the arrangement of letters
meant which was the main thing.
