Today modern pages support picking one of three colors derived from the site theme (soft, neautral, strong). We likely won’t be investing in the option to add arbitrary other colors as a section background, violating the site’s theme. For the other suggestions, please open a unique uservoice suggestion (e.g. support section background images)

would be great to have the ability to add a background image to a row and at least let us use the theme color in a column and not just the full row.
