Just quickly created a nord based theme for @betula. Nothing special.

html,main {background-color:#4C566A}
main article {background-color:#D8DEE9}
article {background-color:#E5E9F0;color:#2E3440}
nav, nav a {color:#E5E9F0 !important}
a,a:hover,a:visited {color:#2E3440;text-decoration:underline}
textarea, input {background-color:#ECEFF4;color: #2E3440}
