Color

Text tokens meet WCAG AA (4.5:1) on the surfaces they are used on, in both themes: text-secondary, text-tertiary and every palette text color (<color>-text-secondary, <color>-text-accent-primary, checked on bg-primary, bg-secondary and the color's own tints) are tuned for it, and white text sits on the *-bg-solid fills (blue-bg-solid, red-bg-solid, green-bg-solid, orange-bg-solid, gray-bg-solid) with text-on-solid. text-disabled is exempt, as WCAG allows.

Money and status text by contract tone: text-n-text-success ("+$1,240.00"), text-n-text-danger ("Overdue", "−$80.00"), text-n-text-warning, text-n-text-info. They are aliases of the tuned green / red / orange / blue -text-secondary colors and pass 4.5:1 on bg-primary, bg-secondary, bg-elevated and the popover background in both themes. From code that takes a tone, use the toneText map: <span className={toneText[tone]}>…</span>.
