shadcn/ui Cyan theme colors: primary oklch(0.52 0.105 223.128) & chart tokens
shadcn/ui Cyan: primary #007595 light / #005f78 dark (oklch(0.52 0.105 223.128)). 20 of 22 checked pairs meet WCAG AA 4.5:1 (light 9/11, dark 11/11). Copy the accent overrides on the neutral base as OKLCH, @theme mapping or hex.
Cyan is an accent theme: it overrides primary, secondary, the chart colours and sidebar-primary, and sits on top of a base colour. Every other value below comes from the neutral base (shadcn's default), and the contrast audit uses that combination. Source: shadcn/ui (MIT, © 2023 shadcn); all themes.

Contrast audit (WCAG 2)
20 of 22 checked pairs meet AA 4.5:1. Pairs with a translucent side are skipped. A suggested fix keeps hue and chroma and moves the foreground's lightness to the nearest AA value, using the same logic as the contrast checker.
