Set solid colour background

Using the hitchcock theme,
Instead of using a “header image”, I want to set a solid colour(say white) background to the entire site (not individual posts or pages).

Adding additional css as below is always getting overwritten.

.site {
  background-color: #ffffff;
} 

Adding an blank white image to the “header image” also didn’t work, as there was an added gradient.

Does anyone have any suggestions?
