Under warm 2700K interior light High Grass 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 1.56:1 and against black 13.46:1, 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.
#e6ff9b · #bbdd00 · #95b000 · #728800 · #516100 · #333e00
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.
#aef78b · #bbdd00 · #cabc00 · #cc9f00 · #c78200 · #c16500
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.
#bbdd00 · #61c0a5 · #819a00 · #008369 · #4c5b00 · #004435
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.
#eaf6c9 · #bbdd00 · #9fb361 · #874bd3 · #424f00 · #283100
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#bbdd00 · #b1abbe · #777e64 · #4b4754 · #1b2104 · #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.
#f3f0fb · #cac6d4 · #9e99a8 · #251f30 · #05010d · #bbdd00
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c0f0f1 · #bbdd00 · #f534db · #5e845a · #3d3d68 · #1e0509
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#cfe9ff · #bbdd00 · #a9b1df · #9f4f97 · #383d5d · #150f04
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#bbdd00 · #8db4d2 · #0082c1 · #890045 · #3e001c · #000510
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#BEDA59 · #C1D77F · #C5D39E
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.
