When you think about color palette, a carefully chosen set of colors that work together to create a unified look in a space. Also known as color scheme, it’s the invisible backbone of every room that either feels calm or chaotic—no matter how expensive the furniture is. A good color palette doesn’t just look nice; it changes how you feel in a space. It can make a small room feel bigger, a dark corner feel cozy, or a dull living room feel alive.

Also known as natural tones, they’re the new way to bring calm into busy homes. You’ll see them in bathrooms, bedrooms, and even living rooms, paired with wood, linen, and clay finishes.

Navy, forest green, or even a warm terracotta can make it pop without overwhelming it. And if you’re wondering why your gray walls feel cold even with a cozy rug, it’s because gray is being replaced. Beige, with its subtle warmth, is the new neutral taking over. It’s not about being trendy—it’s about creating a space that feels like home, not a showroom.
