Alternative Theme to Wellness

Hi,

I am very new to all of this and have designed a site for my wife using this theme (https://daisythemes.com/theme/wellness/) I really like but there are problems (can’t change the header colour etc) and there is no documentation, support or forums so I would like to change theme.

Are there any alternatives that look the same? I like the clean design, I like the featured posts, testimonial sliders etc.

Thank you!
