Caption text, which almost nothing passes.
WCAG 2.1
6.40:1
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 45.7
Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.
Colour difference
ΔE00 51.1
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #1d0200 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 6.35:1, ΔE00 49.0.
deuteranopia
Ratio 6.42:1, ΔE00 49.2.
tritanopia
Ratio 6.40:1, ΔE00 51.3.
The weakest of the three is protanopia, where the two are ΔE00 49.0 apart against 51.1 for a trichromat — still clearly two colours.
