Part of the accessibility testing plan is the following step:
Turn on Contrast Themes: Accessibility -> Contrast Themes > Choose Aquatic (similar to High Contrast Black) theme or Desert (similar to High Contrast White) theme
Does the page look good?
Is it hard to read any of the text (because the color contrast isn't good)?
Is there sufficient contrast between elements (i.e. are there any elements that are black on black, similar color on similar color)?
Choose black theme or white theme (whichever one you haven't shown before)
When turning on the 'Aquatic` high contrast theme setting, most of the example page becomes unreadable - the background of the page goes from white to a very dark grey.
