Under warm 2700K interior light Dark Olive shifts subtly: drifts toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.7), so it is a lighting-stable choice.

Against white it measures 11.34:1 and against black 1.85:1, 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.
#979f78 · #727a4f · #4f5726 · #373e02 · #121600 · #010100
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.
#477662 · #3e6445 · #3a5127 · #373e02 · #342d00 · #2c1e00
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.
#93b6a8 · #8b9367 · #3c7f68 · #3e5b50 · #373e02 · #1f2400
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.
#b8bca8 · #959a7f · #746697 · #373e02 · #1d2013 · #060800
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f2f0f8 · #b8baaf · #848288 · #505347 · #373e02 · #232228
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.
#f2f0fa · #c9c7d2 · #9d9aa6 · #23202e · #04020b · #373e02
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#b2e2df · #f536ee · #648d67 · #424a7e · #373e02 · #21060d
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f3efff · #a7b9e2 · #9c739c · #415076 · #373e02 · #2d1c2d
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e5f4ff · #93c0dc · #a97084 · #6e4152 · #373e02 · #0e2633
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#373D15 · #383C21 · #383B2B
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.
