Deep color gives weight to stillness. TIDELINE 05 — Deep Slate layers navy, blue-gray, light gray, and charcoal in a restrained horizontal composition. Within the subdued palette, a fine white line and quiet stippling create just enough movement for the surface to breathe. Rather than emphasizing darkness, the work explores the spacious calm held inside deeper tones. 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.
