Under warm 2700K interior light Subnautical shifts subtly: leans toward purple; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.1), so it is a lighting-stable choice.

Against white it measures 15.5:1 and against black 1.36:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black 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.
#839bc0 · #5b769f · #34527f · #012253 · #001036 · #000013
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.
#004b62 · #003759 · #012253 · #0f1142 · #10022e · #0b0019
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.
#bda9cc · #7695c4 · #8865a0 · #3c5a87 · #463751 · #012253
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.
#e7bd7a · #727f93 · #4e607b · #374251 · #012253 · #010b22
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7f1e8 · #a9b1bd · #77736c · #343c48 · #012253 · #141009
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.
#f8f1e6 · #d3cbbf · #aaa193 · #392e1d · #170d00 · #012253
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c6ddbd · #c9be36 · #7666a2 · #2c3c2a · #012253 · #030f15
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fdf0dc · #daa285 · #79782c · #5d2c0e · #012253 · #121100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeded · #de9d9d · #558148 · #234518 · #012253 · #220608
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
