Colour is hugely important in branding and logo design. In our guide to colour theory, we look at how colours can generate different emotions. We’ve also looked at examples of great uses of colour in branding and how to choose a colour for a logo.

But we’ve often focused on what colours brands use – not on what colours they don’t use. A new report takes an interesting alternative approach by attempting to identify the least used colours in logo design. And while some of these colours may be little used for good reason, their rareness could also make them options to consider for brands that want to differentiate themselves in a crowded marketplace.
