Under warm 2700K interior light Waterfall shifts subtly: leans 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 2.65:1 and against black 7.91:1, 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.
#c8fff6 · #80ddd0 · #3ab0a2 · #189083 · #00685e · #00423b
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.
#80cee2 · #5bc0c5 · #3ab0a2 · #439c7d · #4b865c · #507040
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.
#9ac0d8 · #3ab0a2 · #2e8e83 · #006893 · #005049 · #042f44
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.
#b6eee5 · #a8c4bf · #3ab0a2 · #ad5e73 · #35645e · #25433f
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbeef1 · #3ab0a2 · #738481 · #534a4c · #102320 · #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.
#fceef0 · #d5c4c7 · #a9979b · #311c21 · #0d0103 · #3ab0a2
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d3dcb7 · #3ab0a2 · #679265 · #c32335 · #40293b · #190b03
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c7d7f9 · #3ab0a2 · #d06162 · #796376 · #303049 · #041115
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f5eeff · #3ab0a2 · #8b73a9 · #703f00 · #311800 · #03000a
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#59ACA0 · #6FA89F · #81A39D
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.
