Under warm 2700K interior light Plutonium shifts subtly: leans toward yellow, loses intensity; 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 1.42:1 and against black 14.83:1, 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.
#d7ffd1 · #35fa00 · #26c300 · #1b9700 · #106d00 · #054500
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.
#91ffc0 · #35fa00 · #9fd200 · #b2b100 · #b59400 · #b07900
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.
#35fa00 · #00cac7 · #21af00 · #008584 · #0f6b00 · #004646
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.
#35fa00 · #da30f5 · #4e7848 · #0c5e00 · #033c00 · #001d00
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#35fa00 · #c0acc3 · #6b8667 · #544656 · #082604 · #030005
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.
#f7eff8 · #cfc5d0 · #a397a4 · #2a1d2c · #08010a · #35fa00
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ecf0ca · #35fa00 · #adc38b · #eb2f9c · #47395e · #220604
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f6e4ff · #35fa00 · #cc809b · #9162c8 · #473b56 · #0f0e03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#35fa00 · #95b4eb · #2572ff · #91001e · #420007 · #000012
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#6DF35C · #90EB83 · #AAE2A2
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.
