When it comes to finding the best LED color for studying, many people believe that blue light is the way to go. However, new research suggests that green light might actually be better for focus and concentration.

Biology - how do color lights stimulate our brain?

Different colors stimulate different areas of our brain. It happens because different colors trigger different chemical reactions in our bodies. Our brain is made of billions of neurons or nerve cells. Every neuron has a certain function, so every color stimulates the neurons that are related to it.

For example, purple light can stimulate the part of your brain responsible for your vision. This means you'll see more clearly and perceive the world better when you're under purple light.

Color lights and your mood

When we hear, see or feel a color we are drawn to it; it triggers an emotional response within us. Although we may not know exactly what causes our emotions toward certain colors, studies show that exposure to different colors can cause different moods in humans (and animals!). For example, Green takes the mind towards growth and harmony, red makes people think of energy and passion.

There are also many studies that show how colors can affect our mood and emotions. For example, one study by the University of British Columbia found that people feel happier in rooms with yellow walls. And a study by Kansas State University found that people felt more energetic in rooms with green walls.

Additionally, studies show that different color light therapies can even improve symptoms of certain mental and physical conditions.

Colors and mental health

A study by the University of Utah found that blue light therapy improved symptoms of depression in 50% of their participants. Additionally, a study by the University of Surrey found that red light therapy improved anger management and hostility issues in prisoners.

Colors and physical health

Studies have also shown that colors can be helpful in healing physical ailments. A study by the University of Texas found that blue light therapy improved psoriasis symptoms. And a study by Harvard Medical School found that green light therapy helped to improve seasonal affective disorder (SAD).

Best color LED lights for studying are blue

According to a study published in the journal Applied Ergonomics, the green light has a more positive effect on cognitive performance than blue light. The study found that when participants were exposed to green light, they performed better on tests of attention and working memory.

So if you're looking for a way to improve your focus while studying, try using a lamp with a green light bulb. You might be surprised at how well it works!

Although it's not an exact science, the absolute best color for studying is generally considered to be blue. Despite recent findings of green light, there are several reasons why this is the case.

First of all, most people naturally associate studying with a desk lamp on their table. Desk lamps give off bluish light because this color has a long wavelength and scatters more easily than other colors in the spectrum. Since it lights up every corner of your desk at once, you won't miss any important details when you study under its glow.

Blue light also helps your brain produce melatonin, which is beneficial for concentration on dull tasks like studying or taking exams. It's a neurotransmitter that helps regulate your sleep-wake cycle, or in other words, it tells you when to get tired and when to feel more awake.

However, there are still some disadvantages associated with using green light bulbs instead of blue ones. For one thing, green is harder to see than blue. If you've ever taken an eye test and been told that you need glasses with a stronger prescription because you have trouble distinguishing between two shades of green, you'll know what we're talking about.

Green are second-best color lights for studying

It is the most effective color for productivity and has no known disadvantages. Additionally, it has a positive effect on cognitive performance. In the past few years, scientists have found out that green light can also be useful for increasing melatonin levels. So if you're studying at night, using a lamp with a green bulb might not hinder your performance as much as you think. In fact, it could even improve it!

Green light boosts focus and concentration The reason why green lights are recommended for study rooms is that they increase attention span and help people concentrate on their work. That's because green light promotes activity in the parietal cortex, which controls visual information, sensory perception, and spatial sense. When we're exposed to too much blue light, this area becomes less responsive to stimulation, which can lead to problems with focus and concentration.

Green light also tends to flicker more than blue or white lights because it's lower in intensity. Brightness is measured in lumens, and since a green LED puts out fewer lumens per watt than a blue one does, it has a much harder time lighting up your environment.

In addition to this, many people find that working under the glow of green light isn't as enjoyable as being bathed in the familiar blue glow of a desk lamp.

Whether it's just a matter of getting used to the different color spectrum or whether there really is something special about associating studying with blue light that makes it easier to concentrate, many students just can't get past their own personal biases and preferences when it comes to choosing a light bulb.

How do other LED colors affect the human brain?


It reduces anxiety and stress, but it also can lead to boredom. Red colors are thought to be one of the least effective colors for productivity. While it does have some benefits, such as the fact that it can help you stay awake, red light is also known to cause eye strain and can even lead to headaches.


It is a balance of all colors and is the most natural. It is the most effective for productivity and has no known disadvantages.


It is less stimulating than blue or green light, making it ideal for relaxing or creative tasks. Some people find that yellow light can be distracting when used for studying or working on detailed tasks.


It is a good color for focus and creativity. It can also improve moods.


This color is said to be helpful for improving mental clarity and reducing eyestrain. This color has some helpful effects for humans, such as reducing eyestrain. However, it isn't as commonly used as other colors like blue or green.


Although this color doesn't have any specific effects, it is often seen as the most natural and beneficial one for humans. It is the most popular color in the world and is considered to be a perfect balance of all colors. It is often used as a study light because it doesn't have any specific effects on the human brain.


Blue is the most popular color in the world and is known to have a lot of positive effects on human beings. It is often used as a study light because it increases attention span and helps people concentrate on their work.


Red is the least popular color in the world and is often seen as having negative effects on humans. It is often used as a study light because it reduces anxiety and stress levels.

Best lights for studying: Warm or cool tone?

If you're struggling to choose between a cool white LED and a warm white one, the difference is in the amount of blue light that each bulb produces. If your main goal is to reduce eye strain when working or studying but still want access to all-around bright lighting, then go for a pure white LED with around 4,000 K (Kelvin). These bulbs are closest to natural daylight.

If you want to concentrate on tasks that require creativity, relaxation, or a chilled-out atmosphere, then choose a LED with a lower color temperature of around 2,700 K. This will give you a warm, yellowish light that's less harsh on the eyes.

LED lights come in all different colors, and each one has its own effect on the human brain. In general, blue light is the most stimulating and beneficial for focus and concentration, while green light is more relaxing and less distracting.

However, there are many different factors to consider when choosing a study light bulb, so it's important to think about what kind of environment you want to create for yourself. Do you want to be stimulated and alert, or calm and focused? Do you find yourself getting distracted by white light from other bulbs, or do you prefer the pure whiteness of a natural daylight LED?

These are all things to consider before choosing your color, but as this article has shown, there's no single correct choice. In the end, it's up to personal preference and what kind of environment you want to create for yourself. However you decide to go about it, just remember that each color will have its own set of consequences and benefits on your health and productivity!

Other light considerations

If you want to improve the focus and concentration of your employees in the office, you should think about changing the lights you use.

Although there's no evidence to suggest that anyone color is better than another when it comes to commercial lighting, changing out your bulbs for warmer colors like red, yellow, or orange can help reduce eyestrain and promote creativity. However, be aware that too much warm light can actually irritate people's eyes and make them tired after staring at it for too long.

If you're looking for an inexpensive way to boost moods in your workplace without sacrificing comfort or productivity, adding a few lamps with yellow or purple bulbs might be all you need! So essentially green light will not do anything special but it does have less negative effects.

Tips on how to be more concentrated while studying:

  • try sitting in a brightly-lit area
  • use blue light as it is the most stimulating and beneficial for focus and concentration
  • avoid using electronic devices in bed at night as the blue light emitted from them can disrupt natural sleep patterns
  • take breaks every 20 minutes to stretch your body and move around, as this will help refresh your mind
  • drink plenty of water throughout the day to stay hydrated and focused.

Bottom line

As we can see, there isn't anyone color that is better than another. It all depends on preference and the environment you want to create. To be more productive and focused, try using blue light. To aid creativity and relaxation, use green or yellow. Keep in mind that each color has its own pros and cons to think about before making a choice.
