Against white it measures 2.42:1 and against black 8.69:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white 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.
#e8f3ff · #a4cef8 · #7dabd8 · #5881a8 · #385c7f · #1a3a58
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.
#9cd7e7 · #89c2e0 · #7dabd8 · #7c94c3 · #7a7dac · #746992
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.
#7dabd8 · #8b829d · #496e91 · #564375 · #153654 · #1f162e
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.
#dfefff · #bdcbd9 · #7dabd8 · #a57b4c · #52677c · #3a4856
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7f1ea · #7dabd8 · #838c95 · #57534e · #1b232b · #020100
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.
#f8f0e8 · #d2c9c0 · #a89e94 · #34281c · #120700 · #7dabd8
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#e4f5d1 · #eedc7e · #7dabd8 · #4e57a1 · #46322a · #051216
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fdefe1 · #7dabd8 · #ae7d6e · #5f5413 · #3d1305 · #070400
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecef · #7dabd8 · #ae7a83 · #465c27 · #182800 · #070001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#87AACE · #90A9C3 · #98A8B9
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.
