Copper has been such a huge metal choice in the last year. The undertone in the metal is warm with a mix of brown, orange, and a slight hint of blush pink, which make it go so well with pastel. Its reflective property can open up the space and make it bigger and brighter.
Mixed with pink pastel, Copper seems so become so subtle but so clean in its lines are finishes.
These are a few pieces I found, which can change up your space with small touches.
