carlosdel123 Hi
It depends on the palette you're using and the headings in the place you want to change.
Let me take the section 1 as sample:
1/ In Layout settings >> edit Section 1 section >> Palettes tab >> you will see a list of palettes there so you can choose
2/ To edit the style for text/headings in one of above palettes, you go to Theme Color settings >> Palettes >> and edit color there.
In case this 'Section 1' is set to None - not use any palette, it will inherit the style defined in template:
/ja_purity_iv/scss/tpl/theme.tpl.scss
Look for this line:
--headings-color: var(--t4-gray-900);
