The primary color linked to boosting serotonin, the brain's "happiness chemical," is yellow, mimicking sunlight to uplift mood, increase optimism, and improve focus, with orange and pinks also promoting happiness and warmth, while greens, blues, and even earthy browns offer benefits like calm, balance, or security, influencing overall emotional well-being.
The color yellow helps release a chemical in the brain called serotonin. This means yellow is a great color for uplifting mood, improving concentration, and increasing metabolism. However, yellow can also tire the eye due to the amount of light reflected, and should be used in small doses to avoid “color fatigue.”
Blue – Calming and Stress-Reducing Benefits for Mental Health. Blue is often considered one of the most calming colors, widely associated with tranquility and peace. Studies have shown that exposure to blue can reduce stress and anxiety, lower heart rates, and help individuals feel more relaxed.
3 Colours that Improve Concentration & Productivity
Yellow is energizing and radiates positivity. It plays to our emotions and lifts confidence levels so is excellent for getting you into the right mood for producing great work. As the strongest psychological color, you might want to opt for yellow tones to stimulate your creativity.
Avoiding colors that can induce anxiety is a good start. Stay away from bright, bold, and intense colors. Colors like red and orange increase anxiety and stress, sometimes even fear. Red and orange are associated with an emergency that can elicit images of emergency vehicles with their lights and sirens on.
For example, Buscemi has found that blues, greens and muted brown tones tend to be great choices for both adults and children with ADD and ADHD.
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.
Among all colors, blue stands out as the top choice linked to intelligence. From deep navy to soft sky blue, this shade evokes calmness, focus, and dependability.
For instance, a study from the University of British Columbia found that when participants were exposed to yellow during learning tasks, they reported higher levels of alertness and were better at retaining information compared to those studying in neutrally-colored environments.
Cool colors, like blue, green and purple are linked to calmness, sadness and indifference. Colors can trigger these arousal states and emotions.
Red, orange and yellow are all warm colors and are generally thought to evoke feelings of happiness, optimism, energy and passion. Yellow-y sunshine might lift your mood, while red roses might get you in the mood. Warm colors also rev you up!
Choosing the right paint for your walls can positively influence your mood and reduce stress. Cool colours such as blue and green can create a calming environment as they evoke feelings of serenity. Additionally, warm colours like orange and yellow are linked to happiness and optimism.
Ways to increase serotonin levels include:
Dopamine colors refer to vibrant, energetic hues that stimulate the brain and trigger the release of dopamine—a neurotransmitter associated with feelings of happiness and motivation. Think of electric blues, bold reds and zesty yellows. These colors are inherently attention-grabbing and energizing.
YELLOW: Optimism and Happiness
Yellow has been psychologically proven to boost energy, awareness, and even metabolism! It stimulates our creative process, which can help us get “unstuck” and make quick decisions. It's a seriously powerful color when it comes to colors that represent positive energy.
The study showed that exposure to blue color led to an increase in the average percentage of participants' intelligence quotient (IQ). The increase doubled with increasing exposure time to blue color.
As mentioned earlier, the four main personality colors are red, blue, green and yellow. Yet only 5% of people can be defined by just one color. We usually match e.g. the characteristics of commanding red and analytical blue or empathetic green and inspiring yellow.
Blue. Blue is often associated with calmness and tranquility. It has a soothing effect on the mind and can help reduce stress and anxiety. Blue is commonly used in bedrooms and relaxation spaces to create a peaceful atmosphere that promotes restful sleep and relaxation.
Although black is a potent symbol of dread, it's not the only color associated with fear. Red, known for representing danger and passion, is often paired with black to intensify feelings of alarm or menace. This combination—seen in caution signs, warning lights, and horror-themed branding—triggers heightened alertness.
Aligned with literature, colour Green was found to be inducing most conducive impacts followed by blue, in reducing depression, anxiety and stress levels of participants.
Greens are best used for patients that are in the hospital often. The natural feel of the color can put chronically ill patients at ease, and make their stay a more calm experience. These reasons are why many scrubs tend to fall into the cool-toned color grouping.
The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".
The five gifts of ADHD include creativity, emotional sensitivity, exuberance, interpersonal empathy, and being nature-smart (The Gift of Adult ADD, 2008).
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
