Storefront setting – background color problem

Hi, it seems that storefront customizer, background color setting, add background color not only to body background, but also to this css tags, this create strange problem on some pages (cart, checkout, pagination etc). Screenshot:

Do you have any suggestion how to resolve this in child theme, in function.php?

I found this in storefront/inc/customizer/class-storefront-customizer.php:

			table th {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -7 ) . ';
			}

			table tbody td {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -2 ) . ';
			}

			table tbody tr:nth-child(2n) td,
			fieldset,
			fieldset legend {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -4 ) . ';
			}
			.pagination .page-numbers li .page-numbers.current, .woocommerce-pagination .page-numbers li .page-numbers.current {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], $darken_factor ) . ';
				color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['text_color'], -10 ) . ';
			}

			#comments .comment-list .comment-content .comment-text {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -7 ) . ';
			}
			#order_review {
				background-color: ' . $storefront_theme_mods['background_color'] . ';
			}

			#payment .payment_methods > li .payment_box,
			#payment .place-order {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -5 ) . ';
			}

			#payment .payment_methods > li:not(.woocommerce-notice) {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -10 ) . ';
			}

			#payment .payment_methods > li:not(.woocommerce-notice):hover {
				background-color: ' . storefront_adjust_color_brightness( $storefront_theme_mods['background_color'], -15 ) . ';
			}
