Rainbow

'Rainbow' (にじ) presents Yayanagi's Pop-Uki approach applied to a meteorological subject. The arc of a rainbow offers an opportunity for the artist to exploit silkscreen's strength in rendering smooth chromatic progressions across flat color bands, achieving the spectral sequence with the clarity and control unavailable in traditional woodblock bokashi gradation. In Yayanagi's hands, the rainbow likely functions as both a natural phenomenon and a graphic element — its curved geometry and sequential hues providing strong compositional structure. The pop art sensibility is evident in the reduction of a transient atmospheric event to a bold, stable graphic form, while the choice of subject connects to Yayanagi's broader ecological and landscape interests rooted in his Hokkaido upbringing.
