How Paint Colours can Affect the Level of Light in Your Home


When it comes to deciding on paint colours for your home, it’s not simply about choosing the colours you like best. In fact, there’s a science to the whole process to make sure that the room not only looks good, but that it creates the setting that you desire and fits with your existing features. Another important consideration is lighting. The perceived brightness of a room can be influenced considerably by the way it is painted. Often it’s the case that you might want certain rooms to have softer light tones, while in others brightness is very important. Let’s have a look at some of the things you should consider in house painting.

Light Reflectance Value


The LRV is essentially a measure to what degree a given paint colour reflects light. While all paint colours reflect light, some do so considerably more than others. The scale runs from 0% (very low reflectance) to 100% (very high reflectance). When selecting paint, you should check out the LRV on the bucket to ascertain where it is suited.

Which rooms should be brighter?

This is something that depends on the kind of mood you want to create in a room, how much natural and artificial light it is already exposed to and the function of the room. Bathrooms, for example, are typically painted in high LRV, bright colours such a stark white or even yellow to ensure high visibility. Bedrooms are the same but to a lesser extent. Dining and living rooms often work with warmer lighting.  Expert’s from a professional painting and decorating company can advise you well on the best option as what works best can change on a case to case basis.

Time of day

The appearance and feel of a room can change considerably depending on where the sun is shining (or not shining) from in relation to it. We’ve seen examples where certain paints have lit up a room gloriously in the first hours of the day, only for it to appear gloomy when the sun is over the other side of the house. Different paints are appropriate for different settings and this is something that really needs to be tested before committing to one.

Artificial lighting

As it has been discussed, the appearance of interior paint colour can change drastically depending the amount of and nature of the light that is reflecting off it. There are many different kinds of artificial light that will work better with certain colours. For example, LED lighting is often rather harsh and can mute warm colours. It, therefore, may not be ideal for a lounge room, but could work well in a kitchen or bathroom. Incandescent bulbs bring out warmer tones but cooler colours tend to appear quite dull. If a room is lit by a certain kind of light, the paint colour may need to be tweaked to account for this.

There are many factors at play when it comes to the paint used and brightness in your home. Your painting contractor should be able to work with your requirements and existing aspects of your home to make it work, however having a general idea about how brightness affects the mood of your interior or how to choose colours according to your room space  is very helpful for any homeowner.
