Under warm 2700K interior light John Lemon shifts subtly: drifts toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2), so it is a lighting-stable choice.

Against white it measures 1.11:1 and against black 18.96:1, 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.
#eeff22 · #c7d600 · #a1ac00 · #7b8500 · #585f00 · #373c00
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.
#eeff22 · #fcdd00 · #ffbc02 · #fd9c00 · #f57d26 · #e36447
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.
#eeff22 · #67c5a1 · #8f9a00 · #008864 · #565d00 · #004833
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.
#eeff22 · #cbd2a3 · #a7b257 · #7945d7 · #484e00 · #2c3000
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eeff22 · #d3cfe5 · #929779 · #595665 · #242706 · #010006
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.
#f2f0fc · #c9c7d4 · #9c99a9 · #231f31 · #04020e · #eeff22
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#eeff22 · #d5cbf9 · #9c7aee · #662cbf · #2d0061 · #020200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#eeff22 · #b2e2e7 · #d081d8 · #506993 · #393855 · #051605
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#eeff22 · #abdaf7 · #009fdc · #a1005f · #480027 · #00050d
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#EEFD6F · #EEFA99 · #EEF7BC
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.
