This is a film composed of two elements: 1) simple hand-painted frames and brief strips of hand-painting, and 2) strips of blank colors, which appear as overall hues or color tones filtering light itself rather than any pictured scenes. These two elements are interposed in editing so as to suggest the seasonal changes of tree-leaf (from greens to golds, reds and browns) and the sky (from varieties of warm-to-cold blues).
