Under warm 2700K interior light Opal Green shifts subtly: leans toward yellow-green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.3), so it is a lighting-stable choice.

Against white it measures 5.39:1 and against black 3.89:1, 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.
#8cccac · #5da684 · #157954 · #005c3d · #003723 · #00150a
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.
#449a99 · #268a78 · #157954 · #2c6433 · #354f14 · #363a00
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.
#97ccd9 · #41b3ca · #5e8c97 · #157954 · #015a3c · #003b26
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.
#add7c1 · #c27ba8 · #157954 · #394e43 · #073523 · #01170d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9eef4 · #76857d · #157954 · #524b4f · #14231c · #020001
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.
#faeef5 · #d2c4cc · #a697a0 · #2e1c27 · #0a0106 · #157954
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5d7b2 · #f65d66 · #5e865c · #157954 · #644567 · #1b0903
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffebf7 · #9272a5 · #157954 · #7c313e · #2d0e3d · #120002
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#eff1ff · #797bb2 · #157954 · #7c3618 · #3b0f00 · #01000c
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#337558 · #45725C · #536E60
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.
