Colors have a great impact on the customer perception of a website and their decision-making. You can use color contrasts to get a color combination that goes with the background of your site and attract the audience. If you choose a color for the CTA button that matches the overall website, the visitors might not notice it. For instance, if you have a green website, use blue for the buttons.
