What color is Sherwin Williams Heartthrob?
Sherwin Williams Heartthrob SW 6866 is a saturated raspberry pink with a red base and a noticeable blue-magenta cast. It reads bold and energetic rather than soft, making it better suited to a focal wall, painted furniture, or a powder room than to every wall in a large room. In clear daylight, its pink side comes forward, while evening bulbs can pull it toward a richer berry red. Pair it with warm white trim, pale oak, brass hardware, or black accents to give the color some structure. For a more dramatic look, Heartthrob looks especially good beside deep navy, dark green, walnut, and natural linen.

LRV of Heartthrob
Heartthrob has an LRV of 10.55% 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 10.55%, 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.
