What The Guardian offers by itself
With the Mac set to dark appearance, the page stayed light.
What Cameleon does on The Guardian
- The Guardian stays light when your Mac is dark, so the skin you set for dark appearance recolours it.
- When your Mac is light, The Guardian keeps its own colours unless you set a skin for light appearance, or choose one for The Guardian.
- A light skin, Sunset or Yardage Book, always goes ahead on The Guardian, dark or not.
- Choose a skin on The Guardian and it is remembered for The Guardian; other sites keep theirs.
- Colour only: the layout, the text and the links stay as The Guardian made them.

Measured 3 November 2026 on the page shown, a public one read without signing in, with Cameleon's own engine. Its cookie-consent dialog was taken off first, as it is once a reader answers it. A further 18 pieces of text sit on a background image rather than a colour, which is painted over the colour beneath it, so they are counted as not measurable rather than scored. WCAG AA is 4.5:1 for text and 3:1 for large text. How it was measured, and what it cannot fix.
The Guardian belongs to its owner, who has nothing to do with Cameleon. The captures show its public page, to show the colours.
