What color is Sherwin Williams Perfect Periwinkle?
Sherwin Williams Perfect Periwinkle SW 9065 is a medium blue with a muted, slightly gray cast that keeps it from reading overly bright. Its cool character is most apparent in daylight, where the blue looks clearer, while lower light can bring out a deeper, more subdued appearance. This color gives bedrooms, home offices, and reading nooks enough presence for full walls without making the room feel visually busy. Pair it with crisp white trim, pale gray upholstery, light oak, or brushed nickel for a clean, grounded palette. It can also make a considered choice for cabinetry or a painted accent wall when paired with warmer natural materials.

LRV of Perfect Periwinkle
Perfect Periwinkle has an LRV of 23.07% and refers to Medium colors that reflect a lot of 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 23.07%, 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.
