Change paragraph and Summary title colour on one page

I'd love some help with this one. A customer is experimenting with colour backgrounds for select pages and I need to change the font colour in this one page only:

https://www.leadingedgedc.com/solutions-for-your-business

Until they decide on their alternate block colours, I'm using this Custom CSS:

/* COLOUR BACKGROUND FOR SOLUTIONS FOR YOUR BUSINESS */

#solutions-for-your-business {
background-color: #1e3267;
border-style: solid;
border-color: #d7cbd7;
border-width: 2px;
h2{
  color: white;
}
p {
colour: white;
}
.summary-title {
  colour: white
}
}

In the editor view, the background and H2 colours are appearing as per custom CSS, but the paragraph and Summary title text remain black instead of white. When I check the published page, none  of the custom colours are showing. Have I got the CSS wrong?

Appreciate the help.

Not

Lol. @tuanphan you are a legend, thanks for taking the time to point this out. It was doing my head in! I don't think I've got the .summary-title css right yet but the color fix is done.
