The site-wide color theme can be easily customized by supplying static/css/color.css.
Colors can also be overriden on a per-page basis. This was done for this page as an example, but is probably not advisedāit can be quite jarring, and might bleed though your post preview if you’re not careful.
This page uses:
:root {
--color-image-background: ivory;
--color-highlight-background: darkslategray;
--color-pre-text: darkslategray;
--color-border: darkslategray;
--color-main-text: black;
--color-muted-text: slategray;
--color-image-selected: gray;
--color-highlight-text: ivory;
--color-pre-background: aliceblue ;
--color-box-background: aliceblue;
--color-background: ivory;
--color-image-forground: darkslategray;
--color-disabled-text: slategray;
}
