This is the third and final artwork in the series. The circles are exactly double the size of Nebula 2 (four times Nebula 1).
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.
