How do i change the text color on the text that's red or black by default? (not including body text)

:root{
--dark-orange: #222 /*This will change all of the red text to black*/
}
p b{
color: #FFF /*This will change all the black heading text to white*/
}

font-family: "Times New Roman", Times, Serif; /*You can stick this line in a piece
of code to change the font*/

To change the text of an element you need to first hide the original text and then add your own with selector::after

.mood p b{
font-size:0px
}
.mood p b::after{
content:"Hello";
font-size:100%
}

.url-info p b:nth-child(1) -> Spacehey URL
.url-info p b:nth-child(2) -> the URL
h4 -> The red headings
