Your website is the ultimate way to advertise your business. In order to do that effectively, you need to decide what your target audience is, and choose designs that will garner the best response. An important component of that is your color scheme. Studies have shown that specific audiences respond to colors very differently.
Colors and graphics will greatly impact your conversion rates. As web design experts, we are always concerned about the aesthetics of a website. However, some calls-to-action may not be beautiful, but will convert.

Knowing who your audience is will be a big help in determining colors, but it is also okay to go the safe route and choose universally loved colors. Whatever message your brand sends should factor into your design choices.
