light/ dark mode color

Hi there

i would like to change those colors:

#es .es-story-meta-button:active, #es .es-story-meta-button.active, #es .es-story-mood-preset:hover, .es-side-widget .o-tabs__link:hover, .es-side-widget .o-tabs__link:active, .o-tabs--stacked .o-tabs__item.active > .o-tabs__link, #es .dropdown-menu, #es .btn-group.open .btn, #es .o-pagination > li > a, #es .o-pagination > li > span, #es .es-convo-sidebar-tab > li > a:hover, #es .es-convo-sidebar-tab > li > a:active, #es .es-convo-sidebar-tab > li > a:focus, #es .es-convo-sidebar-tab > li.active > a {

    background-color: #413e4a !important;

}

picture 1 the color background

picture 2 weird colors.. is it possible only to got 1 color?

It would be really cool to could be a able to set all colors (light and dark) in the templates.

Kind regards
