Its #007577 value gives it enough saturation to read clearly on cabinetry or a feature wall without appearing overly bright. In daylight, Water blue shows its teal edge more clearly, while lower light can make it appear darker and more blue-leaning. It suits bathrooms, kitchens, and built-in storage, especially alongside pale oak, brushed steel, soft white, or warm gray finishes. For a stronger contrast, pair this color with clay-toned accessories or natural terracotta surfaces.

LRV of Water blue

Water blue has an LRV of 15.94% and refers to Medium Dark which means that this color reflects very little light. Why LRV is important?

Light Reflectance Value scale illustration

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 15.94%, 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.
