Colour therapy, also known as chromotherapy, is a form of therapy that uses colour and light to treat certain mental and physical health conditions. We can trace this form of therapy back to the ancient Egyptians. They made use of sun-filled rooms with coloured glasses for therapeutic purposes.

Although colour therapy has gained some popularity over the years, it's still not a widely accepted form of therapy in Western medicine. Many medical experts consider it to be pseudoscience or quackery.

There are two major techniques of colour therapy. It can either be done through sight, that is, by looking at a particular colour in hopes that it elicits the desired response in your body or by directly reflecting certain colours on parts of the body.

Colour therapists believe that colour can enter our bodies either through our eyes or skin. Each colour we can see has its wavelength and unique frequency. Each unique frequency has a different effect on people and is used for different purposes. Warm colours are typically used for stimulating effects, while cool colours are used for calming effects.

Certain colours like blue and green are thought to have soothing effects on people who are stressed or anxious. Warm and stimulating colours are thought to boost your appetite when you struggle with having a desire for food. Colours such as red and yellow are believed to boost your energy and make you more motivated. The effects of certain colours on people may range from person to person. Colours most people might find calming or soothing might be anxiety-inducing or depressing to others.
