Water and earth coexist in a quiet balance within a single composition. TIDELINE 03 — Tidal Earth is composed of four horizontal layers that move from deep blue and blue-gray into sand, amber, and brown. Rather than forcing a sharp contrast between cool and warm tones, soft transitions and stippled texture allow the colors to meet gradually. The work suggests both sea and earth while remaining open and abstract rather than tied to a specific landscape. SERIES — TIDELINE TIDELINE is an abstract series that translates the presence of tide, water, foam, sand, and air into horizontal fields of color. Each composition is built from layered color zones whose boundaries remain soft, connected by subtle bleeding and stippled texture rather than rigid lines. A single fine white line acts as a quiet threshold between water and shore, light and shadow, stillness and movement. Rather than portraying a specific coastline, the series uses color and texture to evoke the slow passage of time and the changing rhythm of the tide. ABOUT RITSUKO NISHIMURA Ritsuko Nishimura creates quiet abstract works centered on the relationship between color, texture, and open space. Her process values restraint—knowing where to stop rather than filling every part of the surface. Through layered color fields, subtle bleeding, stippling, and areas of openness, she aims to leave a sense of light, air, and passing time within each work. The compositions remain intentionally open, allowing viewers to bring their own memories and sensations to the experience of the work.
