According to statistics, it only takes 1/10th of a second for us to form a first impression about a person; and websites are no different.
Google’s 2012 study entitled “The role of visual complexity and prototypicality regarding the first impression of websites: Working towards understanding aesthetic judgments” confirmed that it takes less than 50 milliseconds for users to form an opinion about your website. In other words: after only 0.05 seconds the average user has already decided whether he should stay on your website or leave it.
First impressions do matter. The first impression a user gets from your website depends on many factors, such as the structure, the spacing, the fonts and, of course, the colors and color combinations you display on your page.
