Change default body and link text color

From what I see, the links are already black (with red underline though)?

This is because I manually changed the color. Is there a way to change the default so I won’t have to?

Same for body text?

It depends on the theme. Some themes will have an Options screen where you can select the color of the body or links (or many other things).
Other themes have a section where you can add your own, custom CSS styles to add/override the theme’s default styles.
If both options are not available, you may want to look into child themes, that will give you the option to customize your theme (beyond just colors as well).

On this forum, we only support free themes that are available from the WordPress Theme directory, so we can’t help you with the Blogolife theme. I assume you bought a license for it, so you can request support from the theme author — they should help you with that, because support is what you paid for, after all. ??

Blogolife is a free theme. i did not upgrade to the pro version in which you have to pay for.

I am able to select a background color and color scheme through WPlook panel.

I do have custom css manager plug-in installed. Is there a code to override defaults I can enter?

Apologies, my mistake. I was under the impression it was only available as a Pro/paid theme.

You can place any CSS you want in the custom CSS box. A bit like this:

/* MAIN BODY TEXT */
p {
    color: #666;     /* put whatever color you like here */
}

/* MAIN BODY LINKS */
p a {
    color: #a00;     /* put whatever color you like here */
}

I think that did the trick! Thanks for your help!
