What color is Sherwin Williams Ionian?
Sherwin Williams Ionian SW 6754 is a medium-depth teal that sits between blue and green, with a clear, moderately saturated presence. Its green cast keeps it from reading like a conventional navy, while the blue gives it a cooler, water-toned character. In bright daylight, Ionian can appear cleaner and more turquoise; under warmer indoor bulbs, it may deepen into a richer blue-green. It has enough strength for cabinetry, a front door, or a powder room, but can also carry a larger wall when balanced with pale wood or warm white trim. Pair it with sandy beige, soft cream, natural oak, woven fibers, or brushed brass for contrast, or use charcoal and matte black for a sharper look.

LRV of Ionian
Ionian has an LRV of 19.97% and refers to Medium Dark which means that this color reflects very little 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 19.97%, 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.
