Under warm 2700K interior light Ming shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.5), so it is a lighting-stable choice.

Against white it measures 5.21:1 and against black 4.03:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#a1c9ca · #75a3a4 · #407577 · #285a5c · #05383a · #001719
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.
#6995ab · #4a8795 · #407577 · #22665d · #215442 · #214229
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.
#83aad5 · #788a9f · #407577 · #17595c · #003d3f · #0c1d2f
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.
#bdd5d6 · #8fb5b7 · #7c9090 · #407577 · #6f3a3c · #153536
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9efef · #7b8888 · #407577 · #565050 · #172424 · #020101
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.
#e2f7f7 · #b7cecf · #407577 · #002a2b · #000606 · #e44e5c
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#e2f7f7 · #b7cecf · #407577 · #002a2b · #000606 · #eebc4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7ddb7 · #92cb93 · #e860b1 · #407577 · #574269 · #1a0725
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeded · #a1778b · #407577 · #73442b · #361226 · #0f0200
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f9edfc · #957a9d · #407577 · #684c1b · #2f1d00 · #030004
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.
