Change to Theme color after update

After updating my Themes, the header bar and widget backgrounds changed to a blue color. I’m running Bouquet Child that has a default color of 000000, but appeared as a custom leaf green before the update. Not sure what happened, but haven’t been able to effectively make a color change on the site unless it affects the entire page. I am very new to the blog community and looking for suggestions to get the site color theme back. I did go back and look at previous versions, but when I viewed those pages they all had the same blue coloring.
