CameleonYeni

Cameleon is a Safari extension for the Mac that recolours any website with one of five skins: Midnight, Dusk and Legacy (dark), Sunset and Yardage Book (light). The light skins recolour sites that only come in dark, which dark-mode extensions don't do. Every text colour is re-lit to at least 4.5:1 against the furthest surface in the skin, measured on 15 sites with the results published on its site. It changes colour only, never type or layout, and remembers a skin per site. Requires macOS 13 or later with Safari. $3.99 once after a seven-day trial, one licence for two Macs. No subscription, no account.
