Blue light has the strongest impact. Exposure to blue light (and white light, which contains blue light) during the sensitive period can make it difficult for you to fall asleep and stay asleep. Exposure to white light during the day can have positive effects, including boosting alertness and mood.
Orange has a similar effect as red. It has the ability to make you feel more energized and awake, heightening your chances of restless sleep. The color orange is attention-grabbing. It evokes feelings of excitement and energy.
Light from electronic screens comes in all colors, but the blues are the worst. Blue light fools the brain into thinking it's daytime. When that happens, the body stops releasing a sleep hormone called melatonin. Melatonin is nature's way of helping us wind down and prepare for bed.
Research studies discovered red to be the best color light to help you sleep, because it increases production of melatonin as well as full darkness. On the other end of the spectrum, blue is the worst. Despite being a calm-inducing color on most occasions, blue is not suitable for lighting a bedroom.
Among the visible light spectrum, blue wavelengths have the most powerful effect on your sleep-wake internal body clock. Both natural and artificial blue light can boost your alertness and mental sharpness. But too much of it may keep you awake when your body needs to wind down. Block out light to get good sleep.

Green light therapy for improved sleep
Researchers have found that green light promotes sleep while blue light delays it. In a study conducted by Oxford University, green light produced rapid sleep onset in mice - between 1 and 3 minutes.
Amber or soft yellow light helps you sleep better. The hue has an inherent calmness to it and aids in the production of melatonin. It may also be related to an improved overall mood and mental health.
Aside from being energy- and cost-efficient, LEDs offer a safe alternative to traditional bulbs. LED lights are made without the harmful chemical mercury, which you can become exposed to if a traditional bulb in your home breaks. We recommend replacing as many of these bulbs as possible with LED options.
Protect yourself from blue light at night
Use dim red lights for night lights. Red light is less likely to shift circadian rhythm and suppress melatonin. Avoid looking at bright screens beginning two to three hours before bed.
Because of the lifespan of an LED and its energy-saving capabilities, you'll end up saving a lot of money in the long run. So yes, you can keep LED lights on 24/7. Whether it's Christmas lights or strip lights, LED lights are the best option for prolonged usage.
Green – Quiet and restful, green is a soothing color that can invite harmony and diffuse anxiety. Blue – A highly peaceful color, blue can be especially helpful for stress management because it can encourage a powerful sense of calm. Purple – In many cultures, shades of violet represent strength, wisdom and peace.
Red. Red has always been associated with health, vigor, and love and has increased metabolic activity. This trait makes it the perfect appetite accelerator and a prime color for drinks. Being associated with the red color means raised temperature and blood pressure, which leads to increased thirst.
Red – This bright hue is very energetic and stimulates many senses, which lead directly to your appetite. This is why many fast-food chains include red in their signage and decor. Yellow – Many restaurants also include yellow in their decor, as it is known to increase appetite as well.
The best colors for sleep are blue, yellow, green, silver, orange, pink, and white. These colors reduce stress and soothe the nervous system. Try to stick with neutral or pastel shades for a soft, welcoming atmosphere.
Blue and violet light delayed sleep - the onset of sleep taking between 16 and 19 minutes for blue and between 5 and 10 minutes for violet. Dr Peirson said: 'The results meant that mice exposed to blue light had less sleep than those exposed to violet and green light.
Your levels of melatonin, a sleep-promoting hormone, rise in the evening and exposure to light delays the release of that hormone. “The light exposure is, in essence, somewhat disrupting our circadian rhythm,” she says.
Since household LED lights emit blue light, which suppresses melatonin secretion, keeping bright lamps and other lights on through the night can negatively affect your ability to fall asleep, remain asleep, and sleep for an extended period of time.
About one-third of all visible light is considered blue light. Sunlight is the biggest source of blue light. Artificial sources of blue light include fluorescent light, LED TVs, computer monitors, smartphones, and tablet screens.
Most Android devices should have built-in blue light filters that can be enabled or disabled from the Settings screen. However, the feature's availability and options depend on your specific device and version of Android. You should be able to find the filter under Settings > Display.
The blue light emitted by your cell phone screen restrains the production of melatonin, the hormone that controls your sleep-wake cycle (aka circadian rhythm).
