Red is a happy colour which symbolises strength, energy and vitality.
Red is a bright colour that fills the atmosphere with happiness and cosiness, just using it in small items. It is important to know how to use it in order to create harmony. Otherwise, it can be overwhelming.
We can combine red with other neutral colours such as grey and beige. We can even combine it with colours from the same colour-scheme such as maroon, salmon, and orange. In addition, you could be a bit more risky and use colours such as blue or green.
