How can I modify the color scheme of my webpage?

Wondering since there is no option to change the colour scheme on the side, how can I change the colour scheme of this page to another scheme of mine? Or is it easier to just code it in? I just want the text to be teal and the background to be white.
Thank you!

I ended up writing some simple code with the help of GPT and it worked out

{
background-color: #ffffff;
color: #4cb2ba;
margin-left: 5%;
margin-right: 5%;
}
h3 {
color: #4cb2ba;
}
h1 {
color: #4cb2ba;
font-size:35px;
}
