Changing CSS code so it's only page specific

Hello,

Someone helped me solve an issue I was having with the CSS code below. I loved the changes, but I just now realized that the change is being applied to every single page on my website: http://www.inkwellcoach.com.

What i’d like to do is use two different colors for bold fonts on two separate pages, so as to distinguish the services/product. The pages are: http://inkwellcoach.com/work-with-liz/college-essay-maverick/ (bold blue font #7a9cd4 ) and http://inkwellcoach.com/work-with-liz/next-level-scholars/ (bold green font #8a9b0f ). When I emphasize something on the first page, I’d like it to be emphasized in bold blue, and on the second page, bold green. Does that make sense?

Thanks so much!
