Same page, same layout, same words — only the background colours change. Open each one and compare. Nothing here is live; your real site is untouched.
All five keep your gold and your bone text. Only the dark grounds move, so the site stays recognisably yours.
They also fix something by accident: your current site has 36 places where text fails the readability standard. Every one of these palettes has 5 — because setting the greys against a new background meant solving them properly.
Stone is the edge. It is the lightest one that still works. Past it, your gold stops being legible on the cards without changing the gold itself — on Stone it already needed a 4-point lift, which you will not see but which is the point where "a little" runs out.
