"For me, this rule isn’t about bold contrasts but about creating harmony. I tend to lean towards soft, natural tones for the 60%, like warm neutrals or earthy shades, which provide a calm and grounding base. The 30% might be introduced through natural materials, such as wood, stone or linen, which add texture and depth. For the final 10%, I love bringing in handcrafted details, whether that’s a piece of artisan pottery, a vintage find or soft furnishings in complementary tones."
