How do I change the theme color?

[rastiazul]

I've spent hours trying to do this. I did read the documentation several times.
I want to change the default light blue color by editing a file. I forked the files from another repo. This is mine:
https://github.com/rastiazul/github-pages-gallery
I noticed its different than the one here.
Thank you

Hi, you shouldn't have to fork the theme to change colors.
I see you already have a theme.less file. It should just contain the variables you need:

@body-background: #fff;
@highlight-color: #17baef;

You don't have to copy/paste the rest of the styles.
Any variables included in your --theme-style file will override the theme's default values.

I see you also have a custom.css file which isn't referenced anywhere, you can safely delete it.
