changing the color of the navigation under post

Hello, You will notice here on a single post page: https://www.karenwhooley.com/2018/08/win-a-copy-of-coastal-crochet-at-ellen-gormley-go-crochets-you-tube/ That I have the navigation at the bottom in the standard colors of the theme out of the box. I have updated the pagination as you can see here: https://www.karenwhooley.com/news/ How do I make the navigation at the bottom of the single post match the pagination of the archive blog page?
