I feel I should start with an apology for using colour after so many years of black-and-white. And fluorescent at that, which is unforgiveable, and non-archival.
In the notes to the Color Sensor series, I remarked how I don't like backgrounds that don't have interaction with the foreground. That appears to be the case here, but in fact the background value variation is deliberate and echos the colour sequences in the foreground.
The spots are inspired by the Royal Air Force Red Arrows aerobatic formations. These formations are correlated in two dimensions, whereas the marks are correlated in one dimension.
The use of searing acidic colours juxtaposed with cool greys has been a recurring theme, such as in the Grey+ digital experiments, and I've previously called them "nuclear" colours.
