Under warm 2700K interior light Deep Green shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.9), so it is a lighting-stable choice.

Against white it measures 8.61:1 and against black 2.44:1, 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.
#74aa73 · #488549 · #02590f · #003d05 · #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.
#007c68 · #006a44 · #02590f · #2c4300 · #2e3000 · #271f00
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.
#67adae · #009495 · #307070 · #02590f · #003a05 · #001e01
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.
#bd79c3 · #5a6d59 · #02590f · #123513 · #001900 · #000200
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8eef9 · #9dab9d · #665f66 · #02590f · #283527 · #020002
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.
#f7eef8 · #cfc5d0 · #a397a4 · #2a1d2b · #080109 · #02590f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#feebff · #c790cb · #84448a · #02590f · #4b1750 · #000200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e2cbeb · #c2b6d6 · #d97b9d · #625173 · #02590f · #121205
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ebf2ff · #86a6e8 · #9e3d3c · #02590f · #5d0f13 · #000010
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#1F5621 · #2E532E · #394F38
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.
