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

6.24:1

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 -44.3

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 54.5

different colours

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

Nothing to fix

This pair already clears 4.5:1, so #1199ee can stay exactly as it is. Check another pair.

protanopia

Body text

Ratio 6.82:1, ΔE00 57.4.

deuteranopia

Body text

Ratio 5.93:1, ΔE00 54.1.

tritanopia

Body text

Ratio 5.03:1, ΔE00 44.3.

The weakest of the three is tritanopia, where the two are ΔE00 44.3 apart against 54.5 for a trichromat — still clearly two colours.
