Under warm 2700K interior light Java shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.7), so it is a lighting-stable choice.

Against white it measures 3.53:1 and against black 5.95:1, 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.
#a3edec · #71c6c5 · #259797 · #007a7a · #005353 · #002f2f
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.
#75b4cf · #4fa6b5 · #259797 · #278474 · #2e7155 · #345d39
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.
#8fc9fe · #8ca7c1 · #259797 · #187676 · #005858 · #1a344b
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.
#d5f5f4 · #a2d5d4 · #93adac · #259797 · #944c53 · #234f4f
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbeeef · #93a4a4 · #259797 · #716869 · #1e3030 · #030101
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.
#fceeee · #d6c5c6 · #ab9899 · #351f21 · #110103 · #259797
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffeded · #cc8d91 · #259797 · #9a5259 · #4d171f · #000202
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeded · #c48dac · #259797 · #985739 · #471835 · #190300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f9edff · #b392c2 · #259797 · #8b6220 · #3e2700 · #030006
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.
