Under warm 2700K interior light Vitality shifts subtly: drifts toward yellow; 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 3:1 and against black 7.01:1, 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.
#e9f3c1 · #c0cb93 · #8f9b5b · #747f43 · #515a25 · #313804
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.
#9ac6a1 · #92b17f · #8f9b5b · #8c8347 · #846d3a · #785831
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.
#98bcae · #8f9b5b · #727c48 · #0e6951 · #3b4312 · #052d21
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.
#d6deba · #b4b8a5 · #8f9b5b · #76649d · #353a1f · #1a1e0c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f2f0f9 · #8f9b5b · #787a6f · #49474d · #1c1f13 · #010102
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.
#f3f0fb · #cac7d3 · #9d99a7 · #241f2f · #04020c · #8f9b5b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#b1e1e0 · #85b87f · #8f9b5b · #963e85 · #3b406d · #1f050b
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f3efff · #8f9b5b · #6678a3 · #613661 · #0e1a40 · #040004
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e5f4ff · #8f9b5b · #4f7f9e · #6d3249 · #37091d · #00050e
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#909A68 · #919875 · #929781
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.
