Under warm 2700K interior light Dark is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.8), so it is a lighting-stable choice.

Against white it measures 15.63:1 and against black 1.34:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black 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.
#939aa5 · #6d7581 · #4a525f · #1b2431 · #0c141f · #000104
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.
#184859 · #0a3651 · #1b2431 · #0f1337 · #0e0627 · #0a0015
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.
#b8aac5 · #7b93b7 · #816895 · #41587b · #42374c · #1b2431
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.
#debe8c · #737d8d · #505e72 · #38404b · #1b2431 · #020a1c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f6f1ea · #aab0ba · #75726d · #343a44 · #1b2431 · #120e09
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.
#edf2f9 · #c4c9d1 · #969ca5 · #1b2431 · #01030b · #f5b74d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#faf0e1 · #c5ac85 · #8b6c3d · #4c350c · #1b2431 · #050f1f
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#faf0e1 · #d1a58f · #77753f · #552f1b · #1b2431 · #111000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeded · #d3a1a2 · #5d7d51 · #294220 · #1b2431 · #1d0709
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
