Mostly the aircraft seats or interiors are Blue in Color… WHY???..
No matter which airline you fly with or where you seat, there’s one thing all carriers have in common: blue seats.
Despite popular belief, blue isn’t the chosen because it hides the dirt easily. There’s actually a scientific reason behind the choice of colour, and it’s got to do with making your flight as relaxing as possible.
The specific deep shade of blue produces calming chemicals in the body, which reduce the chance of plane-attributed stress and create a sense of wellbeing, The Sun reports.
Colour Psychology experts explained, "Blue is a colour that suggests peace — it’s the colour of the calm sea and the clear sky, both of which are linked to inner serenity, calm and clarity."
Adding: "Blue is also shown to slow heart rate and breathing, so it can be a good colour to aid in meditation or relaxation."
The colour is also said to create a sense of 'trust', which is why people often wear blue outfits to job interviews.
