What color helps the brain focus?


The ability to focus and concentrate is crucial for work, school, and everyday tasks. Some colors have been shown to enhance focus and concentration more than others. The right colors can help create an environment optimized for productivity, learning, and cognition. This article will explore what color is best for focus and concentration and why it has that effect.

The Psychology of Color

Color psychology suggests that different colors can evoke different moods, feelings, and behaviors in people. This is because color is processed in a unique way by the brain. Visual information passes from the eyes to the thalamus and then gets transmitted to the visual cortex. This is where actual color processing takes place. The brain groups similar colors together and gives them meaning.

So while certain colors are physically just different wavelengths of light, our brains cause us to react to them in consistent ways. This is what allows color to impact human psychology and physiology. Specific colors have been found to increase alertness, arousal, focus, and cognitive performance.

Blue Enhances Focus

Studies consistently show that the color blue enhances focus better than any other color. In a study published in Frontiers in Psychology, participants performed a Stroop test (a cognitive task requiring focus and attention control) on computer screens with red, blue, or white backgrounds. The blue background elicited the fastest and most accurate responses, indicating increased attention abilities.

Participants were also the least distracted when the screen background was blue. Other studies using go/no-go tasks, reading comprehension tests, and memory tests have found similar results. The color blue outperforms others in boosting concentration, attention, and the ability to process information.

Why Blue Works

There are a few key reasons why the color blue enhances mental focus:

1. Blue Light Boosts Alertness

Blue light has a unique effect on the brain. The wavelengths of blue light increase activity in brain areas involved in alertness, hormones, and cognition. Blue light-sensitive cells in the retina send signals to the area of the brain that controls our biological clock (the suprachiasmatic nucleus). This area also plays a role in keeping us awake and regulating our sleep.

Exposure to blue light during daytime hours helps maintain optimal alertness while avoiding drowsiness. This activating effect of blue light is partially why electronic devices and screens can disrupt sleep – they emit a lot of blue light. But for boosting daily focus, blue light is very useful.

2. Blue Evokes Calm

While blue stimulates the mind, it also has a calming effect. Multiple studies demonstrate that shades of blue induce a state of relaxation. In one study, subjects reported feeling less overwhelmed and more positive after spending time in a blue room versus a red, yellow, or green room.

Feelings of calmness and contentment are well-suited to maintaining focus. Anxiety tends to divert attention inward and ruminate, whereas calmness allows an outward focus with less distraction. Blue appears to promote the kind of relaxation conducive to attention, as opposed to the sedation caused by other colors.

3. Cooler Colors Are Less Arousing

Compared to warm colors like red, yellow, and orange, cool colors like blue are less arousing or stimulating. The soothing nature of blue likely contributes to clearer thinking abilities. In one study, cognitive performance wasoptimal when test surroundings were rated as neither too arousing nor too subduing.

4. Blue Doesn’t Cause Fatigue

Staring at a bright screen or environment all day can be draining. Blue light, however, does not tend to cause visual fatigue or strain. Unlike warmer long-wavelength lights that lose energy through heat, blue wavelengths are more efficient.

This makes blue ideal for displays, working and learning environments. Blue is not overstimulating but keeps visual cognition energized.

Other Helpful Colors for Focus

While blue seems to have the most scientific support, other cooler hues like green and purple may also provide some benefits for concentration and focus:


Like blue, green represents calmness and relaxation. One study found that completing a cognitive test in a green room improved motivation and boosted scores. The color green may be less stimulating than blue but can still induce a focused yet relaxed state.


Purple is sometimes considered the color of creativity and problem-solving. Less research has been done on how purple impacts cognition. But one study found that exposure to purple light enhanced the concentration and math abilities of children with ADHD.

How to Use Blue for Focus

If you want to harness the focusing power of blue, here are some tips:

– Surround yourself with blue while working or studying

Hang blue posters, display blue stationery items, or install a blue lightbulb. Painting walls blue can help, but solid blocks of color tend to be overwhelming. Try painting just one wall blue instead.

– Use blue computer backgrounds and themes

Set your desktop, laptop, tablet or phone screen to a blue background. Opt for cooler blue hues rather than extremely bright ones.

– Wear blue

Wearing a blue shirt or accessory can help you maintain focus, especially if your environment lacks blue elements. Avoid warmer blues and instead choose cooler shades.

– Try blue lighting

You can find blue-spectrum lighting bulbs designed to boost attention, learning, and alertness. These lights filter out warmer wavelengths and allow blue hues to dominate.

– Consider blue glasses

Special eyewear with colored blue lenses or filters may improve focus. This can help reduce visual distractions and eye fatigue.


Research clearly shows that the color blue enhances and sustains attention, concentration, and mental focus more than other colors. Blue light boosts alertness and calms the mind thanks to its effects on the brain, vision, and our biological clock. Cooler, subdued blues are best for concentration, as they are relaxing but not overstimulating.

Surrounding yourself with blue while working, studying, or trying to concentrate can help boost your cognitive performance and abilities. Give the color blue a try if you want to optimize your mental focus!
