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
3.73:1
Large text only
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 28.5
Clears Lc 15 — disabled or purely decorative text, which is not meant to be read.
Dark text on a lighter ground.
Colour difference
ΔE00 36.2
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#ebf3ff is the nearest colour of the same hue that passes AA on #737054, at 4.50:1. Only the lightness moved, and some chroma was given up to stay inside sRGB — which is the point: your colour stays recognisably your colour.
And to someone missing a cone
protanopia
Ratio 3.70:1, ΔE00 36.2.
deuteranopia
Ratio 3.75:1, ΔE00 37.0.
tritanopia
Ratio 3.74:1, ΔE00 43.7.
The weakest of the three is protanopia, where the two are ΔE00 36.2 apart against 36.2 for a trichromat — still clearly two colours.
