Ghost Writer on Neon Boneyard

#bcb7ad on #dfc5fe

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

1.29:1

Fails AA

Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.

APCA

Lc 11.2

Below Lc 15: the draft treats this as not text.

Dark text on a lighter ground.

Colour difference

ΔE00 25.4

different colours

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

What the text colour has to become

#5d5950 is the nearest colour of the same hue that passes AA on #dfc5fe, at 4.50:1. Only the lightness moved — which is the point: your colour stays recognisably your colour.

And to someone missing a cone

protanopia

Body text

Ratio 1.26:1, ΔE00 25.1.

deuteranopia

Body text

Ratio 1.30:1, ΔE00 24.6.

tritanopia

Body text

Ratio 1.30:1, ΔE00 6.3.

The weakest of the three is tritanopia, where the two are ΔE00 6.3 apart against 25.4 for a trichromat — still two colours, but a closer call than it looks to you.
