how do I do this ?

Please explain this

For the channel list, change the 'primary_module_subheader_background' StyleVar to the colour of your choice.

For the modules, change the 'module_header_background' StyleVar

That screenshot is from my site.

For the channel list, it's sharing the background stylevar with other elements. So if you change it, it will change in all elements.

That's why I changed it via css_additional template.

.forum-list-container .category-header {
   background: #019dce;
}
.forum-list-container .category-header . category {
   color: #fff !important;
}

Btw, I answered this exact thread here.
