A striking portrait rendered in vibrant electric blue dominates the center of this square composition. The figure appears ethereal and otherworldly against a tropical backdrop featuring a lone palm tree and bands of sunset colors - orange, yellow, and deep turquoise. The subject's elongated form is painted in deep cobalt tones, with glowing reddish eyes and delicate golden linear details tracing the features. The background suggests a coastal scene, with horizontal bands of ocean and sky creating a dreamlike tropical setting. The intense blue coloring of the central figure, combined with its spectral quality, perfectly embodies the "phantom" referenced in the title, while the seaside setting and vivid palette capture the "sky-blue" aspect.
