Under warm 2700K interior light Metropolis shifts subtly: takes on a orange cast; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.1), so it is a lighting-stable choice.

Against white it measures 6.96:1 and against black 3.02:1, 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.
#b3aba4 · #8e857d · #61584f · #473f37 · #272019 · #0a0603
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.
#847d54 · #7d673c · #61584f · #673e24 · #562c22 · #431d1e
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.
#b0b79a · #8e9b66 · #737a61 · #61584f · #553816 · #381f00
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.
#cdb8a4 · #729cc4 · #61584f · #443a30 · #2e1d09 · #0f0601
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ecf3f9 · #b7afa7 · #707478 · #61584f · #484037 · #010204
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.
#f5f1ed · #cec9c5 · #61584f · #2d2721 · #0b0603 · #f3a548
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#e8f3ff · #92b5d5 · #4e779d · #61584f · #234461 · #120500
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e8f3ff · #85baca · #686f9f · #61584f · #094957 · #010007
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e2f7f4 · #84bdb7 · #7f6896 · #61584f · #4a385c · #000202
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#514941 · #413A33 · #322C26 · #241F19 · #16120D
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.
