It’s old news by now -- design is absolutely essential in communicating messages and emotions in your marketing.
The psychological impact of color in particular is a popular topic and design consideration for most marketers (especially when it comes to conversion rates), but unless you are a designer by trade or an art lover, it’s unlikely that you’ve thought deeply into the effects of shape.

These shapes make you feel things; they elicit emotions.
Companies like yours can easily capitalize on these inherent effects to communicate your brand and values through your logos, but in order to do that, you first need to have a thorough understanding of the most common interpretations of different shapes.
