WCAG 2.1
6.47:1
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 -56.7
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 67.9
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #ff9977 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 5.28:1, ΔE00 54.0.
deuteranopia
Ratio 7.15:1, ΔE00 67.9.
tritanopia
Ratio 8.55:1, ΔE00 90.9.
The weakest of the three is protanopia, where the two are ΔE00 54.0 apart against 67.9 for a trichromat — still clearly two colours.
