Under warm 2700K interior light Prismarine shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.5), so it is a lighting-stable choice.

Against white it measures 5.34:1 and against black 3.93:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#8ccac9 · #5ca5a4 · #117777 · #005b5b · #003636 · #001515
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.

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.
#acc7e0 · #78a9d6 · #71889e · #117777 · #005858 · #003b3b
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.
#aed6d5 · #b8757a · #117777 · #3a4e4e · #073434 · #021717
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faefef · #778685 · #117777 · #544d4d · #142323 · #030101
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.
#fbeeef · #d4c5c6 · #a99999 · #321f21 · #0e0203 · #117777
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d3d7b1 · #8fc88a · #f532ba · #117777 · #5d4872 · #170625
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeded · #a0728c · #117777 · #743e25 · #360f28 · #130200
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f8edfe · #92769f · #117777 · #6a470c · #2f1c00 · #030005
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

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.
