To introduce an earthy pink into your palette, I suggest using a shade that complements the existing warm browns and golden tones while adding a soft yet grounded element. Here’s a suitable earthy pink option:

Suggested Earthy Pink Color:

• Dusty Blush ( #D1A6A1 ) - A warm, muted pink with subtle gray undertones that evokes a sense of softness and warmth, reminiscent of rose petals or sun-kissed earth.
