Website Background Color – Any reliable method to change it? [SOLVED]

[Faxopita]

I use the Solarized palette. Here's my config then (taken from guohua zhong):

Code:

FILTER: DarkMode

s@(^[^;]*?(?:<head[^>]*?>|<body[^>]*?>|<script[^>]*?>[^>]*?</script>))@<script>\n\
(function () {\n\
    'use strict';\n\
    document.addEventListener('DOMContentLoaded', function (e) {\n\
    GM_addStyle('html * {background: transparent !important; color: \#819090 !important;} a:link {color: \#FCF4DC !important;} a:visited {color: yellow !important;} a:hover {color: \#A57706 !important;}');\n\
GM_addStyle('html body {background: \#0A2933 !important;}');\n\
    });\n\
})()\n\
</script>\n$1@i

Thanks again for your support.
