Against white it measures 3.42:1 and against black 6.13:1, so black 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.
#c5eeac · #9ac77d · #669841 · #4e7b29 · #2e5604 · #173200
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.
#68c19d · #61ae72 · #669841 · #707f1b · #716600 · #6a4f00
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.
#76b4ac · #669841 · #4f7831 · #005b54 · #1e3d00 · #00221e
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.
#e4f7d8 · #b9d7a7 · #9faf96 · #669841 · #824d9b · #3a512b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f6eefb · #9ca796 · #669841 · #706b73 · #273121 · #020003
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.
#f6eff9 · #cdc5d2 · #a198a6 · #281d2e · #07010b · #669841
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#acdcd9 · #7dae82 · #669841 · #532fd8 · #293b66 · #041121
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#aed9e9 · #b593a3 · #669841 · #5547aa · #2e3d5e · #05150e
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e9f3ff · #74a6e3 · #669841 · #ab4856 · #57071c · #00051a
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
