The colours in your bedroom can have a significant impact on your sleep quality. While individual colour preferences vary, research suggests that certain colours promote positive emotions and associations, while others have a negative impact on our mood and sleep. Cool colours like blue, green, purple, white, and beige are often recommended for bedrooms as they are calming and can put your mind at ease. Warmer colours like red, orange, and yellow can also aid sleep, but only if they are dimly lit. Bright shades of these warm colours can have the opposite effect, stimulating the mind and making it harder to fall asleep.

Blue is a calming colour that may alleviate insomnia
Blue is often associated with tranquility and serenity, such as that evoked by a clear blue sky or calm waters. As such, it is considered a calming colour that can help alleviate insomnia.
Research has shown that blue can induce a drowsy state, though the reason for this is not yet fully understood. One theory is that blue is associated with nature, and we tend to feel relaxed when surrounded by nature. Another theory is that blue promotes positive emotions and associations, which can help to calm us down as we prepare for bed.
However, it is important to distinguish between blue light from electronic devices and blue as a paint colour. Blue light from phones, laptops, and TVs can inhibit melatonin production and disrupt our sleep-wake cycles, making it harder to fall asleep. On the other hand, light shades of blue paint in the bedroom are recommended to promote relaxation and improve sleep quality.
While blue is generally considered a calming colour, individual colour preferences should also be taken into account. Some people may find other colours, such as green or white, more soothing and conducive to sleep. Ultimately, the best bedroom colour is one that promotes relaxation and positive emotions, helping to create an ideal environment for restful sleep.

Red is stimulating and may induce excitement or danger
The colour red is often associated with danger, excitement, and the fight-or-flight response. It is a stimulating colour that can induce excitement or make it difficult to relax.
Red is a colour that demands attention and can increase brain activity. It is associated with high energy and can make people feel restless or energised. For this reason, it is often not recommended for bedrooms, as it may make it harder to fall asleep. However, some research suggests that red light can help people fall asleep and improve sleep quality.
Red light, for example, does not affect circadian rhythms and is one of the best lights to use at night. Exposure to red light can improve sleep and reduce the likelihood of feeling tired and disoriented in the morning. It can also increase melatonin levels, which is the sleep hormone that regulates the body's internal clock.
While red light can be beneficial, bright red light can suppress melatonin production. Therefore, it is important to use dim or warm red lights rather than bright or cool-toned reds.
Overall, while red is a stimulating colour that may induce excitement, the use of red light can be beneficial for sleep.

Green is associated with nature and can reduce stress and blood pressure
The color green is often associated with nature and is believed to have a calming effect on people. Research has shown that exposure to nature can positively impact human health and well-being. For example, indoor plants, which are typically green, may help reduce stress, lower blood pressure, and boost cognition.
Green is often associated with hope, serenity, calmness, and inner peace. A recent study found that wearing green-colored glasses for 15 minutes before a dental procedure reduced anxiety, stress, and pain in patients. All the subjects used to be afraid of the dentist, but those who wore green-colored glasses felt more comfortable during treatment.
The color of your bedroom may also affect your sleep quality. Cooler colors like blue, green, purple, white, or beige may help you relax and put your mind at rest. On the other hand, colors like red, orange, and bright yellow are associated with high energy and may increase brain activity, making it harder to fall asleep.
While the color of your bedroom walls can impact your sleep, it is also important to consider other factors such as lighting and personal color preferences. Some people may find certain colors relaxing, while others may find the same colors annoying or depressing. Therefore, it is essential to choose colors that promote positive emotions and associations for you.
Overall, green is a color that is associated with nature and can help reduce stress and blood pressure. It is often linked with positive emotions and can create a calming atmosphere, making it a good choice for improving sleep quality.

Purple may promote productivity and creativity, but not relaxation
Purple is a cool colour that can promote productivity and creativity, but it may not be the best option for relaxation. While purple is often associated with royalty, luxury, and elegance, it may not be the best choice for a bedroom colour if you're looking to wind down and relax before bed.
Research by UK-based Travelodge found that those who slept in purple rooms got less than six hours of sleep per night on average. While purple may spark creativity and productivity, it may not be the best choice if you're looking to relax and get a full night's rest. This is likely because purple is a stimulating colour that can energize and excite, making it challenging to wind down and prepare for sleep.
When it comes to promoting relaxation and a good night's sleep, other colours may be more effective. Colours like blue, green, white, and beige are often recommended as they are calming and can help put your mind at ease. Blue, in particular, is associated with tranquility and nature, which can induce a drowsy state and promote positive emotions. Green is linked to hope, serenity, calmness, and inner peace, making it an excellent choice for reducing anxiety and stress.
While purple may not be the ideal colour for relaxation, it can still be incorporated into your bedroom design in subtle ways. Consider using purple accents or accessories rather than painting the entire room purple. This way, you can still enjoy the creativity and productivity that purple inspires while creating a relaxing environment conducive to a good night's sleep.
Additionally, it's worth noting that colour preferences vary from person to person, and cultural norms can also influence our emotional responses to colours. So, while purple may not be the best choice for relaxation according to current research, personal preferences and associations with the colour can also play a role in its impact on sleep.

White is associated with positive emotions and can help clear your mind
While there is limited research on the connection between colour and sleep, bedroom colours may influence sleep by affecting our emotions. Psychologists have long studied the impact of colour on people's emotional states, and have found that energy and mood are influenced by colour.
White is technically not a colour, but the combination of all colours across the full visible light spectrum. It is often associated with positive emotions such as peace, security, safety, and relaxation. White may be a good choice for a bedroom due to these associations. Some people also associate white with a lack of emotion and emptiness, which may help clear the mind before sleep.
However, it is important to note that too much white can make it hard to fall asleep, as it can reflect surrounding lights and make it difficult to close your eyes. Ultimately, the best bedroom colour for sleep is one that calms you down as you prepare for bed, and this can vary from person to person.
Other colours that are often considered calming and relaxing include blue, green, and purple. These colours are associated with nature and can evoke feelings of tranquility. On the other hand, colours like red, orange, and bright yellow are mentally stimulating and may increase brain activity, making it harder to fall asleep.
