Caption text, which almost nothing passes.
WCAG 2.1
6.30:1
Passes AA for body text

Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.

This pair already clears 4.5:1, so #0c121b can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 6.74:1, ΔE00 47.9.
deuteranopia
Ratio 6.06:1, ΔE00 44.5.
tritanopia
Ratio 6.03:1, ΔE00 46.7.
The weakest of the three is deuteranopia, where the two are ΔE00 44.5 apart against 48.6 for a trichromat — still clearly two colours.
