Against white it measures 9.83:1 and against black 2.14:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#91abb5 · #698691 · #42626f · #254855 · #01212b · #00050a
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#376e6c · #195d66 · #254855 · #073854 · #102745 · #111735
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#b0b6d3 · #6fa1b4 · #6f77a7 · #585c73 · #254855 · #002e3d
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#b3c9d1 · #c69078 · #53646a · #254855 · #0c2b36 · #001018
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f0ec · #9aa5aa · #5f5a57 · #254855 · #222e32 · #030101
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#e6f5fb · #bdced5 · #90a3ab · #254855 · #000b13 · #f0773c
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#e6f5fb · #bdced5 · #90a3ab · #254855 · #000b13 · #ebbd4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7dcb7 · #96ccc2 · #d5944d · #895851 · #254855 · #041110
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeee6 · #c69498 · #745427 · #254855 · #461d22 · #130700
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#feecf5 · #bf95ac · #625d27 · #254855 · #312d00 · #040002
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
