Body text at this size
And the smaller size most interfaces actually use for paragraphs — the size that decides whether a pair is usable.
Caption text, which almost nothing passes.
WCAG 2.1
8.70:1
Passes AA for body text
AAA too. Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc -58.8
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 69.8
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #fb7efd can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 7.17:1, ΔE00 59.5.
deuteranopia
Ratio 9.53:1, ΔE00 66.8.
tritanopia
Ratio 10.81:1, ΔE00 76.2.
The weakest of the three is protanopia, where the two are ΔE00 59.5 apart against 69.8 for a trichromat — still clearly two colours.
