Hi ludo974
1 - The background and link belong to the Secondary Palette of template, you can go to backend settings of template >> Theme Color tab and configure theme as you wish
For the button on the right, you can use this custom css:
.head-action a.btn.btn-primary {
background-color: #ea4f4f !important;
color: #fff !important;
}
and change to your desired color
2 - The background color will be inherited from settings in above Secondary palette
For the title, use this:
.t4-section-1 .text-primary {
color: #fff !important;
}
3 - Try this:
.acm-features.style-3 .acm-feature-intro .container-inner:before {
background: #E1DBD5 !important;
}
.acm-features.style-3 .acm-feature-intro .feature-action a.btn.btn-lg.btn-primary {
background-color: #6c93bb !important;
color: #fff !important;
}
and change the background color as you wish.
