Under warm 2700K interior light Spearmint shifts subtly: drifts toward green; 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 2.2:1 and against black 9.53:1, 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.
#ccffed · #8bdcc3 · #64bfa4 · #3b8e77 · #176854 · #004334
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.
#94e0e8 · #78d0c8 · #64bfa4 · #68a981 · #6b9363 · #6b7c4a
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.
#64bfa4 · #6c93a2 · #327e69 · #005c75 · #004334 · #002430
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.
#bcd4cc · #64bfa4 · #b6708f · #487366 · #2d5347 · #1b342c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faeef3 · #64bfa4 · #84938e · #5b5457 · #172722 · #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.
#fbeef3 · #d3c4ca · #a8969d · #2f1c24 · #0b0004 · #64bfa4
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffecf3 · #64bfa4 · #b57c94 · #7e3d5c · #3f0d27 · #000201
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e7d3b1 · #64bfa4 · #c26cd1 · #8f706d · #433040 · #041404
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f2f0ff · #64bfa4 · #9087bb · #7f451c · #3c1700 · #020009
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.
