The palettes in the feed now show the contrast level according to WCAG 2.0 for small text as '--' for less 4.5, 'AA' minimum 4.5:1 and 'AAA' minimum 7:1.
Before it has only shown 'AA' if any two colors would pass the contrast check for small text.
Additionally the palette creation shows the contrast level and the contrast ratio of the most contrasting pair of colors within the palette. The mockup for text contains this pair of colors.
