Under warm 2700K interior light Neptune shifts subtly: loses intensity; 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 4.64:1 and against black 4.53:1, so white 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.
#8fd3f9 · #5dacd7 · #007dac · #006187 · #003d57 · #001d2c
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.
#46a7ae · #2093ae · #007dac · #2a659c · #374e88 · #3a396f
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.
#a9a5f6 · #8d8cb3 · #007dac · #005e83 · #00425d · #211d40
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.
#b4e0fa · #e29561 · #007dac · #415865 · #0a3c52 · #051f2c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbefe8 · #81919a · #007dac · #605853 · #172730 · #060200
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.
#fbefe8 · #d6c9c1 · #ae9f96 · #3d2c20 · #1b0a02 · #007dac
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d6d6b0 · #f7777a · #7485b9 · #007dac · #794f67 · #02082e
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeee4 · #c07772 · #007dac · #735400 · #4a050a · #0e0600
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecf3 · #ba7692 · #007dac · #5a5f00 · #252800 · #0b0003
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#337CA0 · #4A7A94 · #5B7888
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.
