What color is Sherwin Williams Nautilus?
Sherwin Williams Nautilus SW 6780 is a clear, mid-tone blue with a noticeable blue-green cast that keeps it from reading like a standard sky blue. Its cool, fresh character is softened by enough green to give the color a lightly aquatic appearance, especially in bright daylight. In north-facing rooms, Nautilus may look crisper and slightly bluer, while warmer artificial light can bring out more of its teal side. It has enough saturation for a powder room, laundry room, or painted built-in, but can also cover bedroom or bathroom walls without feeling too dark. Pair it with clean white trim, pale oak, woven natural fibers, and soft sand or muted coral accents for contrast.

LRV of Nautilus
Nautilus has an LRV of 41.85% and refers to Light Medium colors that reflect half of the incident light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 41.85%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
