Dragon’s Fire on Midnight Edition

#fc4a14 on #0c121b

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

5.48:1

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 -40.8

Clears Lc 30 — the floor: below this the draft considers text not readable at any size.

Light text on a darker ground — the negative sign is the polarity.

Colour difference

ΔE00 55.1

different colours

Above 10 — related only in the sense that both are colours.

Nothing to fix

This pair already clears 4.5:1, so #fc4a14 can stay exactly as it is. Check another pair.

protanopia

Body text

Ratio 3.72:1, ΔE00 43.4.

deuteranopia

Body text

Ratio 6.44:1, ΔE00 58.5.

tritanopia

Body text

Ratio 9.45:1, ΔE00 75.5.

The weakest of the three is protanopia, where the two are ΔE00 43.4 apart against 55.1 for a trichromat — still clearly two colours.
