What effect does the color of aluminum roller shutter doors have on indoor light?

1. Basic optical properties of color

1.1 Principle of light reflection and absorption
The influence of color on indoor light mainly comes from the principle of light reflection and absorption. When light shines on the surface of the rolling shutter door, rolling shutter doors of different colors will reflect and absorb different proportions of light.
White rolling shutter door: White has a high reflectivity and can reflect most of the visible light, with a reflectivity of about 80%. This makes the indoor light brighter, especially suitable for places with insufficient lighting, and can effectively increase the indoor light intensity.
Light-colored rolling shutter door: such as light gray, beige, etc., with a reflectivity between 50% and 70%. These colors will absorb part of the light while reflecting light, making the indoor light soft and avoiding excessive glare, suitable for environments with moderate light requirements.
Dark-colored rolling shutter door: such as black, dark blue, etc., with a low reflectivity, usually between 20% and 30%. They will absorb most of the light, making the indoor light relatively dim, suitable for spaces that need to create a quiet and private atmosphere, such as bedrooms, lounges, etc.
Transparent or translucent roller shutters: These roller shutters allow light to pass through, with a light transmittance of 70% – 90%. They can also provide a certain degree of privacy protection without affecting daylighting, and are suitable for places that require good daylighting and a certain degree of visual transparency, such as commercial display areas, studios, etc.

Choosing the right roller shutter color according to actual needs can effectively adjust the indoor light and create an ideal lighting environment.

2. Reflection characteristics of different color aluminum roller shutters

2.1 High reflectivity of white roller shutters
White aluminum roller shutters are widely used because of their high reflectivity. Studies have shown that white surfaces can reflect about 80% of visible light, which means that most of the light is reflected back into the room, significantly increasing the indoor light intensity. For example, in a basement or north-facing room with insufficient daylighting, installing a white roller shutter can effectively improve the indoor light and make the space appear brighter and more open. In addition, the high reflectivity of white roller shutters can also help reduce the absorption of indoor heat in summer, reduce air conditioning energy consumption, and improve energy efficiency.

2.2 Low reflectivity of dark rolling shutters
In contrast to white rolling shutters, dark aluminum rolling shutters have a lower reflectivity, usually between 20% and 30%. Dark surfaces absorb most of the light, making the indoor light relatively dim, which is suitable for spaces that need to create a quiet and private atmosphere. For example, in places such as bedrooms, lounges or conference rooms, installing dark rolling shutters can effectively block external light and create a comfortable rest or work environment. In addition, while absorbing light, dark rolling shutters also absorb a certain amount of heat, so they can play a certain role in heat preservation in winter and help regulate indoor temperature.

These colors not only reflect light, but also absorb some light, making the indoor light soft and avoiding excessive glare, which is suitable for environments with moderate light requirements. For example, in places such as offices or classrooms, light-colored roller shutters can provide sufficient light while avoiding excessive light causing discomfort to the eyes.
Transparent or translucent roller shutters: These roller shutters allow light to pass through, with a light transmittance of 70% to 90%. They can also play a certain role in privacy protection without affecting the lighting, and are suitable for places that require good lighting and a certain degree of visual transparency, such as commercial display areas, studios, etc.

3.2 Color selection to reduce indoor brightness
In places where you need to reduce indoor brightness and create a quiet and private atmosphere, it is equally important to choose the right color for the rolling shutter door.
Dark rolling shutter doors: Dark rolling shutter doors, such as black, dark blue, etc., have a low reflectivity, usually between 20% – 30%. They absorb most of the light, making the indoor light relatively dim, and are suitable for spaces that need to create a quiet and private atmosphere, such as bedrooms, lounges or conference rooms. For example, installing dark rolling shutter doors in the bedroom can effectively block external light and create a comfortable resting environment.
Color matching and environmental coordination: In addition to choosing a single dark rolling shutter door, you can also adjust the indoor light by color matching. For example, installing a dark rolling shutter door in a room with light-colored walls can create a visual contrast, further reduce the indoor brightness, and also play a decorative role.

4. The impact of color on indoor light quality

4.1 Softness of light
The color of aluminum roller shutters has a significant impact on the softness of indoor light. Studies have shown that roller shutters of different colors will change the softness of light due to the intensity and angle of the reflected light when reflecting light.
Light-colored roller shutters: The reflectivity of light-colored roller shutters such as light gray and beige is between 50% and 70%. These colors can reflect part of the light and absorb part of the light, making the reflected light softer. For example, in places such as offices or classrooms, light-colored roller shutters can effectively avoid the discomfort caused by strong light to the eyes and provide a comfortable visual environment.
Dark-colored roller shutters: Dark-colored roller shutters, such as dark blue and black, have a lower reflectivity, usually between 20% and 30%. They absorb most of the light, and the reflected light is less and softer, which is suitable for spaces that require a quiet and private atmosphere, such as bedrooms or lounges. This soft light helps to relax the body and mind and reduce visual fatigue.
White roller shutters: Although white roller shutters have a high reflectivity and can reflect about 80% of visible light, the reflected light is relatively strong and may cause the light to be too glaring. Therefore, in environments that require soft light, white roller shutters need to be used in conjunction with other measures (such as curtains or blackout cloth).

4.2 Uniformity of light
The color of aluminum roller shutters not only affects the softness of light, but also affects the uniformity of light distribution in the room. Uniform light distribution can avoid uneven light and dark in the room and improve the overall lighting quality.
Light-colored roller shutters: Light-colored roller shutters can reflect and scatter light, so that the light is evenly distributed in the room. For example, light gray roller shutters have a moderate reflectivity and can evenly reflect light to every corner of the room to avoid partial overbrightness or overdarkness.
Transparent or translucent roller shutters: This type of roller shutter has a high light transmittance of 70% – 90%, which allows light to pass evenly while providing a certain degree of privacy protection. In places such as commercial display areas or studios, transparent or translucent roller shutters can ensure uniform light distribution while meeting the needs of lighting and privacy.
Dark roller shutters: Dark roller shutters absorb most of the light and reflect less light, so the light distribution is relatively uneven. In environments where uniform light is required, dark roller shutters may need to be used with other lighting equipment to improve light distribution.
