RAL 180-1 vs Sleepy Blue in Real Spaces
2 real rooms side by side. RAL 180-1 and Sleepy Blue are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Sleepy 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
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Sleepy Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
