Under warm 2700K interior light Elf shifts subtly: drifts toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.5), so it is a lighting-stable choice.

Against white it measures 4.29:1 and against black 4.89:1, so black 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.
#98dec3 · #66b89b · #1b8a6b · #006d52 · #004634 · #002318
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.
#54aaaf · #339b8f · #1b8a6b · #317549 · #3b602a · #3e4a0e
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.
#59c3e2 · #6f9cab · #1b8a6b · #0b6a51 · #004b38 · #002b37
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.
#c6e5d8 · #95c6b3 · #859e94 · #1b8a6b · #813b61 · #184235
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faeef3 · #85968f · #1b8a6b · #625a5e · #192a24 · #020001
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.
#fbeef3 · #d3c4cb · #a7969e · #2e1c25 · #0b0005 · #1b8a6b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d4dbb6 · #f769a1 · #1b8a6b · #516b49 · #3d2d4a · #18051d
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffecf4 · #a880b3 · #1b8a6b · #8f4045 · #381341 · #120001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f1f0ff · #8f89c2 · #1b8a6b · #8b471f · #421800 · #02000c
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#3C866D · #518270 · #607E72
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.
