What color is Behr Thermal?
Behr Thermal S440-7 is a deep, muted blue-green with a smoky charcoal cast. Its low saturation keeps the teal influence subtle, so it reads more like weathered slate than a bright coastal color. In daylight, the cool blue-green undertone is clearer, while lower or warmer lighting can pull it toward dark gray. Use it on cabinetry, a dining room wall, or an exterior front door where its depth can hold its own against light trim. Pale oak, aged brass, soft white, and warm putty tones give this shade contrast without making it feel overly cold.

What are Behr Thermal undertones?
Thermal is a deep, very muted deep teal-gray. The HEX sample has a subtle teal bias, but its low chroma turns that hue into a neutral-looking color rather than a clear teal. Warm bulbs may gray the color down, while cool daylight usually makes its blue or teal direction clearer.

Monochromatic color scheme
This scheme consists of various shades, tints, and tones of a single color. While it offers a perfect combination of hues, without accent décor it may become monotonous.
Lighter shades
Complementary color scheme
This color scheme is a combination of two shades that are opposite each other on the color wheel. The high contrast between these colors creates a vibrant and dynamic visual effect. For the color Thermal with a green hue, complementary colors are those with a red hue close to 6, such as Behr Autumn Ashes and Piano Brown.
LRV of Thermal
Thermal has an LRV of 7.42% and refers to Dark colors which means that this color almost does not reflect 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 7.42%, 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.
