Sage green offers an earthy Light Reflectance Value (LRV ~22.5%) that softens bright south-facing sunlight without feeling dark in neutral ambient daylight.
Colorimetry & Light Reflectance Value (LRV)
About this tool
How to use it
- Choose a curated interior designer color palette or enter custom Hex codes.
- Select your trim and baseboard color to test architectural contrast.
- Toggle between lighting temperatures (2700K Warm Evening, 5000K Natural Sun, 6500K Cool White).
- Select paint sheen (Flat, Eggshell, or Semi-Gloss) for wipeability and luster.
- Inspect the calculated Light Reflectance Value (LRV) and primer recommendations.
Why it matters
Paint colors look vastly different on a physical room wall than on a printed swatch in a hardware store. A shade chosen under fluorescent retail lights shifts dramatically under 2700K incandescent living room lamps or north-facing window light. Visualizing wall-to-trim contrast and Light Reflectance Value (LRV) prevents expensive re-painting mistakes.
When to use it
Use this tool when planning home remodeling, selecting paint colors for bedrooms or living spaces, choosing between matte and eggshell sheens, or matching trim moldings with wall paint.
Good to know
Light Reflectance Value (LRV): Measured on a 0 to 100 scale, LRV represents the percentage of total visible light a paint color reflects. Colors with LRV > 50 maximize natural brightness in dimly lit rooms.
Common questions
What is Light Reflectance Value (LRV)?
LRV is a universal industry measurement (0–100%) indicating how much light a paint color reflects. An LRV of 0 is absolute black (absorbs all light), while 100 is pure reflective white. Most residential interior walls perform best with LRVs between 50% and 75%.
Which paint sheen should I choose for living rooms versus bathrooms?
Living rooms and bedrooms generally use Flat or Eggshell (10–25% sheen) for soft, glare-free light diffusion. High-humidity and high-traffic areas like bathrooms, kitchens, and baseboard trims require Satin or Semi-Gloss (40–60% sheen) for moisture resistance and wipeability.
How does bulb color temperature (Kelvin) change wall paint?
Warm bulbs (2700K) accentuate reds, oranges, and yellows while dulling blues and greens. Cool bulbs (5000K–6500K) bring out crisp modern blues and whites while making warm creams appear muted.
When do I need a grey-tinted primer instead of white?
Deep, saturated wall colors with an LRV below 40% (such as navy, charcoal, or deep forest green) require a grey-tinted primer to achieve true color depth in fewer coats.
What is the recommended contrast ratio between wall and trim?
A contrast ratio of at least 3:1 between wall paint and trim creates crisp, elegant architectural definition without harsh visual jarring.
