Orange is fun, it’s playful and will encourage conversation if used in decorating an environment.
Not only does it encourage communication, it also stimulates appetite.
It’s not a colour that works well in business, it’s message is too much about sociability and carefree times and lacks any business sense. But it is noticeable which is why you will see it in high-visibility clothing.
It will grab attention, so is a great colour to wear in a social setting if you want to be noticed, to be seen as warm and inviting (particularly if you’re shy or introverted and find these occasions hard work).
Orange can only ever have a warm undertone as it’s a mix of red and yellow, so those with cool colouring should steer clear of wearing it, but don’t feel that you can’t enjoy it in your life – just use it in your surroundings instead!
