Under warm 2700K interior light Foil shifts only faintly, with no single dominant change; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2), so it is a lighting-stable choice.

Against white it measures 1.77:1 and against black 11.84:1, 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.
#eff2f3 · #c0c3c4 · #a0a3a3 · #7b7d7e · #57595a · #363839
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.
#b1eae3 · #9bdde3 · #c0c3c4 · #84b7d6 · #80a0c4 · #7b8aaf
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.
#c0c3c4 · #9aa2bb · #578e9f · #586593 · #1f5362 · #2a3047
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.
#d7eaf1 · #c0c3c4 · #c18975 · #44656f · #29464f · #16282e
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#c0c3c4 · #aca4a1 · #6b767a · #4a4442 · #121e22 · #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.
#f1f2f2 · #c0c3c4 · #a1a2a3 · #2e3031 · #0e0f10 · #ef6a39
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#f1f2f2 · #c0c3c4 · #a1a2a3 · #2e3031 · #0e0f10 · #ecbd4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c0c3c4 · #b3a29c · #93685a · #673626 · #340f03 · #000408
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c0c3c4 · #b3a29c · #94666c · #5f3d10 · #330c15 · #130600
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#c0c3c4 · #b0a1ab · #8c6780 · #50460c · #221c00 · #040002
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#a0a3a3 · #808283 · #606262 · #404141 · #202121
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
