Under warm 2700K interior light King Lime shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.9), so it is a lighting-stable choice.

Against white it measures 1.65:1 and against black 12.7:1, 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.
#e3ffa8 · #add900 · #8eb300 · #6d8a00 · #4d6300 · #303e00
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.
#82ffb4 · #91ef77 · #add900 · #bfb800 · #c19b00 · #bd7f00
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.
#add900 · #56bba2 · #769500 · #007c67 · #435700 · #003e32
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.
#e1f1c4 · #add900 · #95ae5d · #904cd5 · #3a4b00 · #212c00
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#add900 · #aca5b8 · #717a60 · #494451 · #182004 · #020005
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.
#f4effb · #cbc6d3 · #9e99a8 · #261e30 · #05010d · #add900
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#e7dfb9 · #add900 · #eb31c7 · #5a805d · #3d3a62 · #200508
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c4e3fe · #add900 · #9dafdd · #954d9b · #373c5c · #110d03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#add900 · #88aecd · #007dc0 · #85003e · #3c0018 · #000511
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#B2D656 · #B7D27B · #BCCE99
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.
