Hello,
The fonts and font colors can be changed with a third-party plugin e.g. Easy Google Fonts.
After the plugin installing and activating, go to Appearance > Customize > Typography. Colour of fonts can be changed in the “Appearance” section.
Otherwise, fonts` colour can be changed with below CSS codes added to Appearance > Customize > Additional CSS(change # 000 to the needed colours):
h1 {
color: #000 !important;
}
p {
color: #000 !important;
}
.site .site-wrapper .site-header .site-header-wrapper .mphb_sc_search-wrapper label {
color: #000;
}
Best Regards,
M. Evans
