Under warm 2700K interior light Limoncello shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 1.2:1 and against black 17.52:1, 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.
#bfff00 · #a7e000 · #86b500 · #678b00 · #496400 · #2d3f00
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.
#bfff00 · #dbdb00 · #e2bb00 · #e19d00 · #dc7e00 · #d85b00
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.
#bfff00 · #3abda5 · #6f9700 · #007b69 · #3f5700 · #003d33
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.
#bfff00 · #b6ca99 · #8bad4e · #9d41e4 · #344900 · #1c2a00
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#bfff00 · #cdc3da · #859173 · #585160 · #1c2705 · #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.
#f4effa · #ccc6d3 · #a099a8 · #271f30 · #06020d · #bfff00
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#bfff00 · #b3d8c2 · #78a974 · #522aef · #273862 · #041120
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#bfff00 · #ecc4b7 · #9e6a8d · #6450bd · #33324d · #110d03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#bfff00 · #a3cdf4 · #0092e8 · #9d0045 · #47001b · #000512
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#C7FB65 · #CFF690 · #D7F0B2
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.
