Exposure to white light during the day can have positive effects, including boosting alertness and mood. Red light has no effect on the circadian clock, so you can use a dim red light at night.
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.
1. Blue light. According to a 2017 study in the scientific journal PLOS ONE (9), blue lighting “accelerates the relaxation process after stress in comparison with conventional white lighting.” This study found that stressed people immersed in blue light relaxed three times as quickly as in white light.
Yet by now most of us are also aware that blue light can play a big role in depriving us of sleep, with studies demonstrating the association between blue light and wakefulness.
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.
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.

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.
