Minimalism is an important foundation of Japandi style, so the best colors to go for are warm neutrals, beiges, and off-whites, which provide a serene, tranquil backdrop to the space.You can add depth with subtle accent tones like sage green, terracotta, or soft charcoal. Earthy tones, muted blues, and natural wood finishes will help your space reflect the beauty of the outdoors, a key element of Japandi design.
