When we think about remodeling or redesigning our homes, we often fixate on big projects like adding a fireplace or redoing our home’s concrete and plaster walls. While these remodeling projects will go a long way when it comes to changing up the look of your home, there’s one subtle change you can make that can very well give your home an entirely new look: color rendering.

Color rendering plays a significant role in how things look in your home. Considering how important it is, it’s rather surprising that not everyone knows what it is. However, we’ve prepared a brief discussion on color rendering, its importance to interior design, and the different factors that affect it. 

Color Rendering

Color rendering refers to how things look under a specific light source. It’s important to understand that you may not be seeing objects in their true colors, as the quality of light in the surrounding areas plays a huge role when it comes to how colors are perceived. This isn’t really surprising, considering that your brain and eyes work together to translate light into color.

While perception is rather subjective, there is a more objective way to view color rendering. The International Commission on Illumination (CIE) has developed a Color Rendering Index (CRI) that measures light sources from a rating of 0-100. The index is straightforward: the higher the score, the more accurate the color rendition is.

Importance of Color Rendering

Now, you may be asking how this affects the way you design your home. Well, if you’re thinking about incorporating lots of vibrant shades of colors into your redesigns, then you’ll want to make sure those colors look the way they should under your space’s lighting. 

In these cases, it will be in your best interest to choose a lighting source with a CRI of 90 or higher. If this just isn’t an option, the lowest you’ll want to go when it comes to CRI is around 80. This is because anything below 80 will drastically affect the color quality of the objects that are under the light!

Factors That Affect Color Rendering

Despite the information given above, there are also different factors that affect the color rendering within your home. Let’s address the more obvious factor first.

The type of lighting or bulbs that you use in your home is incredibly important. Remember that different bulbs will have different color rendering. Generally, LED bulbs have the best quality among the light bulbs that are commonly used in residential spaces. Another factor affecting color rendering is the amount of natural light in your space because natural daylight is considered the reference for CRI (which puts it at 100 CRI). As such, you’ll want to utilize natural lighting in your space if you want to get good color rendering. Fortunately, we offer window replacement and patching services.
