The Colour Code: How Hues Impact Your Brain

Have you ever noticed how a certain colour makes you feel? As a certified art therapist, this is a cornerstone of my practice. The connection between colour and our brains is far more than just personal preference; it's rooted in our neurobiology.

Our eyes contain specialized cells called cone cells that detect different wavelengths of light, which we perceive as colour. These signals travel through the optic nerve to the visual cortex in the brain. But the journey doesn't end there. These signals also connect to other brain areas, including the amygdala (involved in emotional processing) and the hypothalamus (which regulates various bodily functions like sleep and hormone release).

This intricate network explains why colours can evoke such strong emotional and physiological responses:

• The Soothing Spectrum (Blues and Greens): These colours tend to have longer wavelengths associated with relaxation. They can lower blood pressure and heart rate, promoting a sense of calm and peace. Think of the tranquility of a blue ocean or a green forest.

• The Energizing Hues (Reds and Oranges): Shorter wavelengths, like those of red and orange, can be stimulating. They can increase alertness, boost energy levels, and even trigger the release of adrenaline. This can be beneficial for focus but might also contribute to feelings of anxiety in certain contexts.

• The Bright and Cheerful (Yellows): Yellow is often linked to optimism and happiness. It can stimulate the brain and promote feelings of joy and creativity. However, it's important to note that intense yellow can sometimes be overwhelming or even induce feelings of anxiety in some individuals.

• The Grounding Neutrals (Browns and Beiges): These earth tones often evoke feelings of stability, comfort, and security. They can create a sense of grounding and connection to the natural world.

In art therapy, we leverage this knowledge to help individuals explore and express their emotions non-verbally. By consciously choosing and working with different colours, clients can gain insights into their inner world and facilitate emotional healing. Pay attention to the colours you gravitate towards and how they make you feel – it's a direct line to understanding your brain's responses!
