Colors. Conversion rate. What do they have to do with each other? Well, a lot. 92% of us say our senses guide our purchasing decisions. And here online, we don’t have touch, smell, taste, or audio. (Some websites have audio. Usually a bad idea, but that’s a topic for another day.) That leaves sight as the only way our visitors can judge us, and that makes picking the best colors for website conversion advantageous.
