Does it
actually work?
A pairing that looks right on white can fail the moment it meets a real background. Put colour behind it, check it against WCAG, and see what happens in dark mode — before it ships.
A quiet revolution in reading
Large text clears the bar at three to one. Body copy has to reach four and a half.
Every letterform carries an argument about how a sentence should feel. Choose two that agree, and the page stops fighting the reader. Choose two that disagree politely, and the page starts to sing.
Contrast is not a matter of taste. It is a ratio between two relative luminances, and a reader with low vision either clears it or does not.
Caption, legal line, or form hint — the size where a pairing quietly fails.

Every mood below ships a pairing and a full light/dark palette, checked against WCAG before it ever reaches you.
