Many people have the experience of carefully selecting the best paint colors for their homes, but when they paint the walls, they are disappointed with the colors. This general phenomenon is inevitably the result of at least one of many visual distortion factors that affect the human eye and change our perception of color throughout the panel selection process. Among the 11 factors of distortion, the light source factor is the factor that has the greatest impact on your ability to successfully select the color of the paint in your room. Therefore, understanding the behavior of different light sources in the interior space of the home is an important secret to choosing the best paint color.
The first point here is that the color we see is actually the result of light reflecting from the surface and entering the retina. When we saw a paper that looked very yellow, we actually saw a yellow light reflected from the paper. This may be because the light source itself is yellow or because the paper is yellow.
In addition, light of a certain color tends to project the color of the paint to this end of the spectrum. We don’t even have to worry about the actual color of the object, we should only worry about the color of the object as it shines on the object. We use different types of lighting to illuminate our homes and businesses, and each type of lighting has a different effect on the colors around us.
Natural light or sun
Natural light or sunlight is the purest source of light most visible to most people (closest to white). It shines from purple to red (imagine a prism) throughout the visible spectrum. The main colors visible in the sun are the dawn from the high red end to the blue end of the noon spectrum and the red orange at night. The undulating effects of daylight can make the paint surface warmer at dawn and dusk, and appear colder and brighter when the sun is at the highest point of the sky. If the sun is covered by weather conditions, these effects of daylight may be further exacerbated. The water in the afternoon and early morning sky caused by various weather systems will cause more red because the sunlight will filter into the atmosphere.
The wavelength in the fluorescence spectrum is different from the wavelength of sunlight that uniformly covers the entire visible spectrum, and is very intense between 490 nm and 590 nm. This means that almost all of the brightness of a fluorescent bulb is green; the rest of the visible spectrum has very little light. This is an important factor in choosing the color of the paint. The color in the painting studio (usually lit by fluorescent lights) will be very different from the color in the home. In addition to being lighter in the store, they have a more green hue. Traditional fluorescent bulbs are becoming less and less common in new homes, even in kitchens and bathrooms. However, fluorescent lamps are rapidly spreading in the form of compact fluorescent bulbs (CFLs).
Incandescent lamps, the light produced by classic light bulbs, are still the most common type of light in most rooms of the house. Incandescent bulbs illuminate more uniformly than fluorescent bulbs over a larger portion of the visible spectrum, but their efficiency increases significantly to the higher end of the spectrum, actually reaching the highest point in the visible spectrum. . At 750 nm, the same edge. However, the performance of the bulb varies. The GE Reveal bulb has a much light distribution across its spectral range, making it significantly redder than its soft white bulb.
Halogen bulbs are most commonly used for headlamps, recessed luminaires (or cans), headlights, tracking lights, chandeliers, headlights, etc. The maximum concentration of halogen light is at a wavelength of about 650 nm, which gives it a reddish hue, just like an incandescent lamp. The red part of the spectrum at 650 nm is not as far as the standard incandescent bulb, but the effect of red is usually more pronounced. This is because the halogen bulb emits much less light in the rest of the spectrum, and more energy is concentrated at this maximum wavelength.
Xenon lights (xenon brenner)
Xenon lamps or xenon brenner are rare in China. They can be used in some focus and track lighting applications; but they are becoming more and more popular, such as bar lights, designed to illuminate countertops in kitchen cabinets. The maximum wavelength of the xenon bulbs is approximately 450 nm, which makes them deeper into the blue (almost purple) range. Like incandescent lamps, xenon bulbs (xenon brenner) emit light over a wider range of visible spectra. They have less than one tip at any wavelength and are generally not as bright as fluorescent lamps. This means that they tend to distort the surrounding colors.
