Light Reflectance Value (LRV) is a measure of the percentage of visible light a paint color reflects or absorbs. It is a measure on a scale from 0 to 100 that indicates how much light a paint color reflects. A color with an LRV of 100 reflects all light, appearing very bright, while an LRV of 0 absorbs all light, appearing very dark. Paint colors with a lower LRV will reflect some light but not tons of light. If a color’s LRV is 10, it will absorb a lot of light and reflect a smaller amount into the room. If it’s 20, it will reflect more than 10, but still not much.
LRV is an attribute of color that measures how much light a paint color reflects and how much it absorbs. It is used by experts to predict how light or dark a color will appear. The higher the LRV number is, the lighter a color will look and the more light it will reflect. The lower the LRV number, the darker the shade will be.
Light reflectance value is particularly important when painting the exterior of a building. High LRV numbers help keep buildings cool by reflecting light and absorbing heat. LRV is measured on a scale from 0, which is black and doesn’t reflect any light, to 100, which is pure white and reflects all light. Absolute black will absorb all light and heat, while pure white will reflect some light into the room, making an average room with average light look reasonably bright but still soft.
In summary, LRV is an attribute of color that measures the percentage of visible light a paint color reflects and absorbs. It is crucial for color consultants, architects, and all types of professionals to consider LRV when selecting paint colors for their interiors.

What is light reflective value in paint?
Light Reflective Value (LRV) is a measure of how much light is reflected by a paint color, with a higher value indicating more light. A solid black paint with no light reflects zero light, while a bright white paint reflects all light is rated at 100. Lighter paint colors have higher LRV values, greater than 50, reflecting more light than darker shades, making them ideal for areas with less artificial lighting. Instead of removing walls or adding windows, painting walls with paint with a high LVR value can make rooms more light and bright.
What is reflective light in a painting?
Light on an object can be direct or indirect, with direct light being the lightest area. Reflected light, which bounces off other objects in the same area, creates a beautiful glow in the shadow areas, separating the object from the surrounding dark area. This light adds dimension and can create a gorgeous bit of variance in dark or uninteresting areas.
In a photograph of a sphere in sunlight, the highlight area directly in the path of sunlight is the lightest, while the left and lower areas show darker light reflected from the sphere’s surroundings. Direct light is always lighter in value than reflected light, so the value of reflected light should not compete with the highlights or lights.
When observing a shadow, look right next to it for reflected light. Sometimes it’s as apparent as on the sphere, while other times it’s not so obvious. In a painting like La Luna, there are many areas of reflected light, some readily apparent and some subtle. The main light source is to the upper left of the setup.
What should be LRV of interior paint?
The Low Reflectivity (LRV) range of paint colors is 0-40, encompassing darker colors that absorb more light than reflected back. The medium LRV range is 40-60, reflecting an average amount of light. The high LRV range is 60-100, reflecting a lot of light. The higher the LRV, the lighter the color, while a lower LRV is darker. These values are used by architects, engineers, interior designers, and color consultants to predict the light or dark of a color in a room and help lighting designers calculate the number and type of fixtures needed. When choosing a new color for walls, consider these values before making a decision.
How does light reflective paint work?
Luminescent paint is a glowing paint that glows autonomously in the dark without the aid of ultraviolet or other light sources. Fluorescent paint starts to glow only when the covered object is exposed to ultraviolet lamps, while light reflective paint starts to glow when the light beam impacts the covered surface. The best reflection effect is seen by the person standing on the side where the light beam is directed. Retroreflective paint is a combination of special light reflective pigment and transparent medium (usually varnish) mixed in a 1:3 ratio.
The varnish can be made from various materials, such as alkyd, acrylic, or polyurethane. The most popular application of retroreflective paint is road marking, where a double-layer application is used, applying a regular white marking line first and then covering it with a light reflective coating. This provides a perfect reference point for drivers at night.
What is the perfect LRV number?
A higher LRV (Light Refractive Index) refers to the amount of light a paint color absorbs and reflects back. Whites in the 70-85 range are ideal for exterior paint, but their effectiveness depends on the amount of direct sunlight and fixed elements in the home. Whites have a high light reflective value, causing them to pick up surrounding colors. If the home receives direct natural light, it will appear lighter and more reflective. A darker paint may require more exterior lighting under a covered porch or entryway, as it doesn’t reflect light. Using various types of lighting can enhance the area.
What is reflection of light in interior design?
Mirrors can be used to reflect artificial light and natural sunlight, enhancing the amount of natural light in interior spaces with limited windows. The placement of mirrors can significantly affect the amount of light created, and they can amplify and diffuse light without creating a chilly or harsh atmosphere. Mirrors can also be used to establish a focal point, highlighting existing elements or standing alone as statement pieces, or to draw attention to a room that doesn’t already have one.
What is light value in interior design?
Light Reflectance Value (LRV) is a measure of the percentage of visible light a paint color reflects from or absorbs into a painted surface. It ranges from zero (absolute black) to 100 percent (pure white). Building and design professionals use LRV to predict color appearance and calculate the number and type of light fixtures needed for interior spaces. The Americans with Disabilities Act (ADA) Accessibility Guidelines recommend a 70 light reflectance value or higher for those with impaired vision, but this is not a strict requirement. Some color combinations in the 60-70 range work well.
What LRV makes a room look bigger?
The use of space-expanding whites, such as Loft White, pale blues, such as Gauze, and cool greys, such as Flint, effectively reflects light, thereby creating the impression of increased space. It is recommended that kitchen cupboards, baseboards, window frames, and bannisters be painted in a gloss finish. Additionally, Intelligent Gloss should be used to reflect light in matte schemes and darker corners.
What is light value of colors?
A pure color, known as a hue, can be adjusted by adding pure black or pure white. The value of a hue is the measurement of the amount of black or white mixed into the color. A darker hue is called a “shade”, while a lighter one is called a “tint”. For example, the color red can be transformed into a pink (red + white) tint or a darker shade called “Burgundy” (red + black). The addition of pure white or black can alter the value of a hue.

What is a good LRV?
Common spaces, such as kitchens and living rooms, typically require an LRV of 60 or higher for brighter colors. However, bedrooms, formal dining rooms, and dens can experiment with lower LRV colors since brightness isn’t necessarily needed in these areas.
In windowless rooms, choosing a high LRV may not be the best choice as the paint color will reflect artificial light, which is usually yellower than natural light. Instead, opt for mid-range LRVs to reduce light reflection and allow the color to read more truer.
Undertones can be classified as color (mainly blue, green, red, and yellow) and tone (cool or warm). Color undertones are the secondary pigments in a formula, and their presence can vary depending on the surrounding light and environment. Cool or warm tones can be more or less apparent depending on the situation, with slightly warm tones evoke a sense of coziness, heavily warm tones can be energetic, and cooler tones can be calm and soothing.
