Can Colours Really Affect Appetite?

Research shows that colours have a psychological effect on humans. But did you know this also goes for your appetite and cravings too? If you are a member of the ‘FitFam’ or if you take your health and the food you consume seriously, you should continue reading.

Yes! Colours have a way of affecting your appetite. Ever wondered why restaurants usually have red table clothes, red wall paints or red interior decorations? They are craftily and subtly trying to use the power of colour to increase your appetite. Even in homes, the right colours can be creatively used in and around kitchen and dining areas to achieve specific objectives, which is why Sandtex Paints offer advisory services at its Experience Centres on a range of colours and hues that would suit individual goals.

Scientists even agree on the fact that colours have a great impact on how appealing and unappealing food is to you. The hypothalamus neuron in the brain, which regulates appetites, starts to fire up when it detects food in and around a particular colour. The glands in the mouth also start to increase saliva production in readiness for eating.

But then, we live in an extremely visual culture with a lot of varieties. While some food colour hues can trigger hunger, other hues actually work to suppress our appetite. Here are some colours that can affect your appetite.


This colour is an appetite stimulator. Studies have shown that people find red coloured foods a lot more appealing than others. This is because red activates appetite so much. No wonder it is usually included in restaurant menus, logos, napkin or tablecloths. Red colour can also do the exact opposite. Studies have also shown that people who eat on red coloured dishware eat less than they normally would. This can be because the red colour is also associated with danger or a warning sign.


This colour is usually associated with being healthy, natural, safe and clean. People tend to think that green foods are healthy, whether or not the food is nutritious. The consideration of Green food as being safe and non-poisonous dates back to the golden era, when our ancestors explored food options. Green is a colour that promotes healthy eating and the brain recognizes it as such. So, we tend to eat them or stock up on them in abundance.


Yellow is usually associated with happiness or excitement. When people are happy or excited, they tend to eat more. The colour stimulates appetite because the brain secretes more serotonin, which is a “feel good” hormone. No wonder restaurants usually have a lot of yellow flowers in or around the restaurant. The yellow colour gives off the feeling of optimism and optimism makes you want to splurge on your food.


According to research, this colour is one of the least appetizing colours and decreases appetite. Although it is a calming colour that helps in soothing distressed feelings, blue coloured food gives off an unnatural feeling to the brain and so the palate is not triggered to even want to try or eat as much. The same goes for foods served on a blue platter. It usually induces less intake of food. If you are trying to cut back on the number of calories you consume each day, put up a blue coloured light in your kitchen. Colour blue is best left for the room where relaxation and calmness are needed.


If you want to squelch any thought of food, this is the go-to colour. Black as a colour might be slimming when it is worn, but it is not one that stimulates hunger. The sight of this colour in food makes you question the healthiness of the food. Black reminds people of food that is burnt or overcooked.
