Dark mode isn’t a second logo — it’s the same files with the color tokens flipped. The mark’s T is a real transparent cut-out, so it inverts on its own. Only one thing actually needs a tweak: the accent, when it’s used as a link.
Set color:#F2EEE8 and the same SVG becomes a light tile with the dark page showing through the T. No dark asset to maintain.
The solid terracotta tile keeps its silhouette on light and dark browser chrome — so it’s the one asset that ignores the theme.
Terracotta #BB5A3C only hits 3.9:1 on dark — fine as a button fill with white text, too dim as a link. Links lift to #C56A4A.
Why two accents? White text needs the darker terracotta under it to stay legible (4.5:1), but terracotta-as-text needs the lighter one to read on a dark background. The button keeps the original; only links shift. Everything here clears WCAG AA.
