What Color LED Light Helps You Sleep Besides Red?

We already know that red LED light may be the most beneficial for sleeping. Many people undergo red light therapy to improve their sleep cycles.

According to research, the red LED light may help with melatonin production, help the body feel calm and relaxed, and improve sleep quality.

Even though red LED light’s wavelength potentially benefits human sleep, each person is different and may react differently. Not all people may improve their sleeping cycle from the red light, which is why there are other light colors possibly beneficial for this purpose.

We will take a look at some of them below.

Yellow LED light color

Even though many researchers have divided opinions, we may say that the second best color besides red for improved sleep is probably yellow.

Yellow is a warm color, and even though it may seem brighter than red, it may still positively affect the circadian rhythm. This color is also associated with stress and anxiety relief, as it creates a feeling of calmness. 

Choosing a soft hue of yellow color for your bedroom may be perfect, and you should avoid too bright and sharp yellow colors as they might have the opposite effect.

Orange LED light color

The next closest color to red is orange. Orange is produced by mixing red and yellow hues, which is why it’s probably the third-best warm color for improved sleep.

The orange LED light is not burdening the eyes and may help produce the sleeping hormone melatonin. With its resemblance to the sunset at the end of each day, the orange color acts as an excellent signal to the brain, telling it that it’s time for sleep.

However, darker orange is better suited for sleeping, and you should avoid bright hues of this color before bed as they might stimulate your brain and disrupt your sleep.

Pink LED light color

The pink color is a hue from a combination of white and red. Even though it’s not a very common color in LED lights, it’s also potentially beneficial for promoting a good night’s sleep.

Soft pink hues are better for this purpose as they may promote a feeling of tranquility and relaxation, while sharp and bright pink may do the opposite. Choosing pink for your LED light will give your bedroom a unique look and feel.

Green LED light color

Green LED light color may also be a good choice for better sleep, although it’s relatively uncommon to find it in any bedroom. Green is not a stimulating color, so it doesn’t adversely affect melatonin production and may promote relaxation and calmness.

This color also falls between the warm and cool light spectrum, with 4,800 degrees Kelvin. It is next to blue, one of the colors you should avoid at night.

Link Between the LED Light Color and Sleep

LED lights and their various colors affect vision. The human eyes possess light receptors called intrinsically photosensitive retinal ganglion cells, or ipRGCs. These cells are types of neurons situated in the retina of the eyes of all mammals, through which they sense light color signals.

These cells are responsible for telling the brain what time of day it is and adjusting the biological clock in every human being.

In the past, when technology was primitive, the human body was better adjusted because its biological clock and cells were more in sync. There were no artificial lights to disrupt its circadian rhythm, causing potential sleeping disorders.

Still, not all things are bad, as some LED light colors impact humans and their psychology differently. Some might even be very beneficial and substantially improve the sleep cycle.

What Color LED Light Isn’t Suitable for Sleeping?

Blue LED light color

Even though the blue color is related to calmness and relaxation, that isn’t true with blue LED light. Blue LED light is not a pleasant color for sleeping because, according to research, it dramatically disrupts the body’s circadian rhythm.

Blue LED light may cause the suppression of melatonin when it is time to sleep and promote eye strain and fatigue.

Due to this, many devices, such as computers and smartphones, implement a blue light filter feature. This shifts the colors of their display to the warmer spectrum at night to help users sleep better and be more relaxed.

White LED light color

White LED light is also unsuitable for sleep, so avoid it before bed. Since white is a blend of all the colors in the color spectrum, evidence exists that it promotes awareness and improved cognitive function.

That is why white LED light might be a good idea for the daytime and should be avoided at night.


Now that we have given you a basic understanding of what color LED light helps you sleep besides red, you can easily choose the one that suits you most.

According to research, a significant factor in not getting a good night’s sleep is the constant use of electronic devices before bed.

So, by reducing their usage and implementing one of the LED light colors of the warm color spectrum, you might be able to get a good night’s sleep and wake up invigorated and full of energy.
