Under warm 2700K interior light Delta Mint shifts subtly: drifts toward yellow-green; in north-facing or shaded light it shifts subtly: leans toward blue-green. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 1.35:1 and against black 15.59:1, 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.
#dcfbe5 · #c5e6cf · #8eaa97 · #6b8473 · #4a5f51 · #2b3d31
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.
#c4f8e5 · #c5e6cf · #b2d5a8 · #adbd8e · #a7a678 · #9e9067
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.
#c5e6cf · #a1c3c8 · #7da98c · #418b95 · #456c53 · #2a4d51
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.
#c5e6cf · #b789ac · #6c7a70 · #445e4d · #293f31 · #142219
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#c5e6cf · #c4bdc2 · #7f8982 · #534f52 · #1a231d · #020101
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.
#c5e6cf · #94a498 · #384b3e · #1a2e21 · #000c03 · #db68c6
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#c5e6cf · #94a498 · #384b3e · #1a2e21 · #000c03 · #f3b94d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c5e6cf · #c9bac5 · #9d7894 · #6a4061 · #32132d · #000601
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c5e6cf · #c9bac5 · #8e7da3 · #733e4b · #281739 · #050001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its high lightness and low chroma make it a natural background or large-surface color. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
