Change homepage Jumbotron text colour

Website link:
How do I change the colour of the main Title text in the Jumbotron section?
Because of the background colour I want to keep it blue but add a silver outline around the text. How do I do this?
Should I create a <h99> and change the css file for h99?
Could you let me know?

hey there

You can use this css:

#header.header-front-page .bottom-header h1 {
color: #be1e1e;
