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
6.88:1
Passes AA for body text
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc -59.1
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 57.3
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #bcb7ad can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 7.26:1, ΔE00 56.1.
deuteranopia
Ratio 6.70:1, ΔE00 54.1.
tritanopia
Ratio 6.24:1, ΔE00 52.9.
The weakest of the three is tritanopia, where the two are ΔE00 52.9 apart against 57.3 for a trichromat — still clearly two colours.
