Against white it measures 2.03:1 and against black 10.35:1, 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.
#c9fff4 · #79dfcd · #58c8b6 · #268f80 · #00685c · #00423a
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.
#96e7f9 · #74d8da · #58c8b6 · #5eb390 · #649d6f · #688652
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.
#58c8b6 · #7399af · #268678 · #006186 · #004940 · #00293b
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.
#c0dcd6 · #58c8b6 · #c3728a · #265b52 · #0a3c35 · #011e1a
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbeef1 · #58c8b6 · #899b97 · #60585a · #172926 · #030001
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.
#fceef1 · #d4c4c8 · #a9979b · #311c22 · #0d0103 · #58c8b6
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7d8b2 · #58c8b6 · #78a977 · #c92dba · #3d3458 · #170727
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffecf1 · #58c8b6 · #b583ae · #8c4034 · #3c1038 · #070000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f4efff · #58c8b6 · #9f8ac2 · #844a06 · #3a1c00 · #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.
