Under warm 2700K interior light Marsh Fog shifts subtly: drifts toward yellow-green; in north-facing or shaded light it shifts subtly: leans toward blue-green. Overall drift across common illuminants is small (max ΔE ≈ 2), so it is a lighting-stable choice.

Against white it measures 1.49:1 and against black 14.05:1, 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.
#e6f7e7 · #c6d8c7 · #97a798 · #738174 · #515d52 · #313b32
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.
#c4f3db · #c6d8c7 · #afc999 · #aab181 · #a39b6d · #99845f
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.
#c6d8c7 · #97babb · #7a9e7d · #368386 · #426245 · #214546
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.
#c6d8c7 · #b58cb5 · #657165 · #3f5441 · #243726 · #0f1a10
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#c6d8c7 · #b9b3b9 · #79817a · #4f4b4f · #19211a · #020102
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.
#c6d8c7 · #97a097 · #3a453b · #1d271d · #010601 · #d172d2
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#c6d8c7 · #97a097 · #3a453b · #1d271d · #010601 · #f3b94d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c6d8c7 · #beb1bd · #927392 · #623d62 · #2e122e · #000200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c6d8c7 · #beb1bd · #82789f · #6c3a4d · #221739 · #040001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#c6d8c7 · #afb5c4 · #6f7ea3 · #703b36 · #38100d · #000008
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its high lightness and low chroma make it a natural background or large-surface color. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
