To stand before the canvases of Amartya (Joëlle Zioga) is to encounter a field where material facture dissolves into an atmosphere of apparition. In her “Blue Collection,” a body of work she confesses is closest to her heart, color is not merely pigment but ontology: a register of being that presses beyond the retinal into the metaphysical. Blue and green, her chosen chromatic poles, are not incidental hues but coordinates of psychic orientation, elemental substances through which memory, dream, and infinity are refracted.
