A colour is synonymous with your brand, and your colour choice not only represents your business but also impacts your followers on a psychological level.
If you haven’t already chosen your logo colours, Google “the colour spectrum” used by interior designers and choose colours from opposite sides of the colour wheel. And it won’t matter if it is the darkest or the lightest shades you choose using this method because the colours will always complement each other.
