Under warm 2700K interior light Melancholia shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.8), so it is a lighting-stable choice.

Against white it measures 12.99:1 and against black 1.62:1, 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.
#87a383 · #607f5b · #3a5c35 · #12390d · #001a00 · #000200
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.
#3d7b83 · #256c67 · #135c4b · #0d4b2e · #12390d · #192600
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.
#7faaa8 · #6c8c67 · #0e7472 · #2c5050 · #12390d · #011e00
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.
#a980b0 · #5d715a · #455043 · #12390d · #081a06 · #000300
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f6eff7 · #afb8ae · #7e7a7f · #41493f · #12390d · #1d181d
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.
#f6eff7 · #cec5cf · #a298a3 · #291e2b · #070109 · #12390d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#faedfc · #c9a7cf · #926b99 · #58395d · #12390d · #0e1e0c
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#faedfc · #b5aedd · #a26681 · #473f6a · #12390d · #28111c
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ebf2ff · #9db6e0 · #a76765 · #673635 · #12390d · #0e192d
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.
