The HARU WordPress theme has a red and dark blue color scheme.
It has an After Header widget area with a full width hero image background. Using the Widget Logic plugin you can display this only on homepage.
You can also set the homepage to be a static page that uses the full-width-content template and you can easily have a business website.
Or you can delete the text widget from the After Header widget area and use it as a blog.
** You need to have Genesis Framework in order to use the child theme. Genesis Framework is not included with the theme.
