Bedroom

Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Gossamer Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Kitchen Cabinets

Gossamer Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
