Before we get into that, let us first see what contrasting colours are. Like the word suggests, contrasting colours are on the opposite ends of the colour spectrum. Taking reference of the colour wheel, this means that they are from opposing categories. For instance red from the warm colours and blue from the cool colours.
With the definition made clear, let’s move onto the actual question. As mentioned above, contrast is for the bold! A contrasting colour scheme can bring in life to a dull space.
But for a contrasting colour scheme to be successful, you have to make sure the colours don’t become overpoweringly bright. Choose two to three colours of your liking, but no more. If you are unsure about the intensity of the colours, then always go for muted shades. Bringing together bright shades of two or more contrasting colours will create chaos. This will turn ‘bold’ into ‘disturbing’. If you do not want to settle for muted tones and want something stimulating, then try having one dominant colour. Mute all the other colours. This will have a vibrancy to it without the cluttering-effect.
