Under warm 2700K interior light Billiard 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 2.75:1 and against black 7.63:1, 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.
#c4fff5 · #71dfcf · #00af9f · #009082 · #00675d · #00413a
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.
#6fcce3 · #42bec4 · #00af9f · #2c9a78 · #408554 · #4a6e36
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.
#92bdd8 · #00af9f · #028d80 · #00658e · #004d45 · #002c42
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.
#acece1 · #a1c2bc · #00af9f · #af556f · #2b625b · #1e413c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fdedf0 · #00af9f · #6d817e · #51484a · #0d2320 · #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 · #d5c4c8 · #a9979b · #311c21 · #0d0103 · #00af9f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d2dbb7 · #87bd88 · #00af9f · #c0232c · #583a54 · #180b03
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffecf0 · #00af9f · #9f6695 · #7f2b19 · #380232 · #080000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f5eeff · #00af9f · #886eab · #6e3d00 · #301700 · #03000b
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#47AA9D · #64A69C · #7AA19A
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.
