This is the third and final artwork in the series. The circles are exactly double the size of Nebula II (four times Nebula I).
Most circles extend beyond the frame, filling the composition so that the overall image feels markedly different from the previous pieces.
The background deepens to a dark orange-red, adding strong character and striking contrast against the circle colours.
The transparency of the overlapping circles generates unexpected colour blends — a signature effect across the series.
