Under warm 2700K interior light Mamba shifts subtly: takes on a magenta cast; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.3), so it is a lighting-stable choice.

Against white it measures 4.94:1 and against black 4.25:1, 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.
#cbc3d0 · #a49caa · #766d7c · #5b5361 · #3a333e · #1b151f
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.
#8d91b9 · #867ba7 · #766d7c · #755274 · #684158 · #58323e
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.
#d79aa8 · #a3858c · #766d7c · #614a6f · #443051 · #32181f
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.
#b2cf9d · #968e9c · #766d7c · #5a4c63 · #3b2f43 · #1e1723
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff3ec · #8f8992 · #766d7c · #565854 · #27212a · #010100
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.
#f4f0f6 · #cbc7ce · #766d7c · #27212a · #060208 · #a3d777
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ecf5e6 · #7e946e · #766d7c · #486033 · #182a05 · #020005
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ecf5e6 · #938d63 · #766d7c · #2a644b · #292400 · #000602
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fcf0e2 · #a38663 · #766d7c · #0d6562 · #002b29 · #120600
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#625A67 · #4E4753 · #3B353F · #29242D · #18141B
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.
