How to Choose Lighting for Paint Colors

How to Choose Lighting for Paint Colors

So, you've just finished painting your bathroom the perfect shade of light blue that took you weeks to decide on. Washed in natural light, your bathroom looks like a calming seaside oasis. But when you turn the lights on at night, it completely loses its soothing affect. Why? Chances are the lighting you currently have installed is all wrong for your new paint colors.

The lighting we choose to use in our homes can have a huge effect on the way we perceive color because it is created by the way objects react to certain wavelengths of light. This is called metamerism. It’s the same reason why you might buy something you thought was black in the store, but in the light of day, you realize it’s actually navy blue. No color is definite or stands alone because any type of light, whether it’s natural or artificial, affects our perception. When considering what kind of artificial light source to use in your home, whether halogen, incandescent, LED, or fluorescent, it’s important to think about how it will enhance or diminish a room’s existing color scheme.

Determine Your End of the Color Spectrum

The first thing you’ll need to do before choosing your light source is evaluate whether or not the paint color in your room falls into the warm or cool part of the color spectrum. If your walls are painted in rich reds, yellows, and other earth tones, you would most likely need a warmer light source. If they’re painted in blues, greens, or other vibrant colors with cool undertones, a brighter, cooler light source is your best bet.

Below describes the kind of light that is generated by each artificial light source.

  • Incandescent: Generates a yellow light that enhances warm tones, but dulls cool tones.

  • Halogen: Produces a whiter light that is comparable to sunlight.

  • Fluorescent: Generally used for cool lighting applications, but is available in warm color temperatures.

  • LED: Can be used against all colors and is flexible across the color spectrum.

Warm Paint Colors


To bring out the richness and warmth of your paint color, choose fixtures and lighting that have a "warm white" color temperature between the range of 2400K and 3000K. The lower the number on the Kelvin scale, the warmer the color temperature of the light will be. Typically, the best lights to use within these color temperatures are incandescent or halogen bulbs that produce a whiter light that won’t distort color as much either way. LEDs and CFLs within the low color temperature range will work as well, but make sure they have a high enough Lumen output to meet the level of brightness you’re wanting.

Cool Paint Colors


To enhance the vibrancy of cooler paint colors, you’ll want to choose lighting with a color temperature that falls between 4000K and 6000K. LEDs and CFLs within this color temperature range are called either “cool white” or “stark white.” If you were to use a light source with a low color temperature against blue or green paint, the color might appear dull and distorted.

Brightness and Color Rendering

The color temperature of a light source isn't the only thing that affects the way we see color; brightness of the light, or Lumen output, does as well. Rooms with darker colors painted on the walls tend to absorb more light than a room with light colored walls and tend to look dull if the lighting is not bright enough. The brighter the lighting, the more the true color of your walls will stand out. However, the dimness or brightness of your room and how it reacts to color is all a matter of personal preference.

Another factor to keep in mind is the Color Rendering Index (CRI) of the light source that you're using. Ranging from 0-100, this index determines how a light source will make a color appear to the human eye. The higher the lamp's CRI, the better it's color rendering capabilities. While standard incandescent lamps usually have a CRI of 100, LEDs have about 80+ CRI, and fluorescents range anywhere from 50 to 90.  As this video shows below, two of the same light sources with differing CRI ratings will cause colors to appear differently in tone.
