Customizing color scheme

[riking (Kane York)]

This should work for you:

@import 'theme_variables';

html {
    background-color: pink; /* white */
}
div#main-outlet {
    background-color: green; /* $secondary */
    margin-left: auto;
    margin-right: auto;
    max-width: calc(1110px + 15px * 2);
}
