Under warm 2700K interior light Noir is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.6), so it is a lighting-stable choice.

Against white it measures 13.95:1 and against black 1.51:1, 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.
#a49f9c · #7f7976 · #5c5652 · #312b27 · #1c1713 · #030201
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.
#594a24 · #51350d · #312b27 · #3c1304 · #2f0809 · #210209
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.
#bebea0 · #ba9379 · #83824c · #7e583d · #484830 · #312b27
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.
#7bb2d3 · #796253 · #53463d · #312b27 · #200d01 · #050100
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ebf3f8 · #bcb1ab · #757a7d · #4b413a · #312b27 · #12181c
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.
#f4f1ef · #cdc9c7 · #a29e9b · #312b27 · #0b0705 · #f29042
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#e4f5ff · #8fbad5 · #4b80a0 · #1c4861 · #312b27 · #241205
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e4f5ff · #86bfc6 · #6478a6 · #054d54 · #312b27 · #0f1628
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e3f7f1 · #8bc1b2 · #7d70a1 · #463c62 · #312b27 · #001c16
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.
